Option A is correct answer.
•Statement 1 is correct. Coverage area of a satellite based system is greater than that of a terrestrial based wireless communication system. A GEO satellite with one single antenna can cover about 1/4th of the earth
•Statement 2 is correct and statement 3 is incorrect. In a satellite link delay from earth to satellite to earth is about 240ms while in terrestrial link it will be far less. But transmission cost in a satellite system is independent of the distance within the area of coverage of the satellite antenna, while in terrestrial system it varies based on the distance.

Option A is correct answer.
•Virtual reality (VR) and augmented reality (AR) are two technologies that are changing the way we use screens, creating new and exciting interactive experiences.
•Statement 1 and 2 are incorrect Virtual reality uses a headset to place you in a computer-generated world that you can explore. Augmented reality, on the other hand, is a bit different. Instead of transporting you to a virtual world, it takes digital images and layers them on the real world around you through the use of either a clear visor or smartphone.
•Statement 3 is correct.

Option C is correct answer.
• Statement 1 is correct. Named in honor of the trailblazing astronomer Edwin Hubble, the Hubble Space Telescope is a large, space-based observatory, which has revolutionized astronomy since its launch and deployment by the space shuttle Discovery in 1990.
• Statement 2 is correct. Telescopes have a particular range of light that they can detect. Hubble’s domain extends from the ultraviolet through the visible (which our eyes see) and into the near-infrared. This range has allowed Hubble to deliver stunning images of stars, galaxies, and other astronomical objects that have inspired people around the world and changed our understanding of the universe.

Option A is correct answer.
• Statement 1 is incorrect. India would become the fourth nation in the world to launch a human spaceflight mission after Russia, China, and the USA
• Statement 2 is correct. The first trial will be unmanned and the second trial will include a female robot named ‘Vyommitra’
• Statement 3 is incorrect. The astronaut suit for the mission is jointly developed by india and russia.

Option- C is correct Answer.
• statement 1 is incorrect. BepiColombo is an mission which comprised of two spacecraft riding together to Mercury to orbit and to study the planet from unique vantage points
• statement 2 is correct. The European Space Agency (ESA) provided one orbiter. The Japan Aerospace Exploration Agency (JAXA) supplied the second orbiter
• statement 3 is correct. Ariane 5 is the launch vehicle used

Option- A is correct answer.
• Statement 1 is correct. While geosynchronous satellites can have any inclination, the key difference from geostationary orbit is the fact that they lie on the same plane as the equator
• Statement 2 is incorrect. Weather monitoring satellites like GOES are in geostationary orbits because they have a constant view of the same area.

Both the statements are correct.
AstroSat is the first dedicated Indian astronomy mission aimed at studying celestial sources in X-ray, optical and UV spectral bands simultaneously. Hence, statement 1 is correct.
It was launched by PSLV-C30 from Satish Dhawan Space Centre, Sriharikota. Hence, statement 2 is correct.

Option A is correct answer.
Pair 1 is correct. Pairs 2,3 are incorrect.
Statement 1 is correct. Quantum computers employ the superposition prinicple of quantum physics. According to this principle, superposition allows quantum objects to simultaneously exist in more than one state or location. Together with entanglement and superimposition capabilities, quantum computers can perform complex calculations more efficiently.
Statement 2 is incorrect. Edge computing can be understood as an efficient complement to cloud computing. While cloud computing relies on data uploaded on a central cloud, edge computing allows advanced on-device processing.
Edge computing moves some portion of storage and compute resources out of the central data centre and closer to the source of the data itself, thereby providing the requisite speed and efficiency in processing. This technology is used extensively in the internet of things environment.
Statement 3 is incorrect. Sharding – dividing a blockchain into several smaller component networks called shards capable of processing transactions in parallel.

Option B is correct answer.
Statements 1 and 3 are incorrect. Statement 2 is correct.
Statement 1 is incorrect. The scheme will provide financial incentive of 25% on capital expenditure for the identified list of electronic goods
Statement 3 is incorrect. The scheme will be implemented through a nodal agency. The nodal agency would do the assessment of the application. Such nodal agency will act as Project Management Agency (PMA) and be responsible for providing secretarial, managerial and implementation support and carrying out other responsibilities as assigned by MeitY from time to time.

Option A is correct answer.
Statement 1 is correct. Statement 2 is incorrect.
The positive indigenisation list includes items that the armed forces — Army, Navy, and Air Force — will procure only from domestic manufacturers (government as well as domestic private sector).
