1 and 3 are correct.

Asteroids are rocky objects that orbit the Sun, much smaller than planets. They are also called minor planets. Asteroids are divided into three classes. First, those found in the main asteroid belt between Mars and Jupiter.
The second group is that of trojans, which are asteroids that share an orbit with a larger planet. NASA reports the presence of Jupiter, Neptune and Mars trojans. In 2011, they reported an Earth trojan as well.
The third classification is Near-Earth Asteroids (NEA), which have orbits that pass close by the Earth. Those that cross the Earth’s orbit are called Earth-crossers. More than 10,000 such asteroids are known, out of which over 1,400 are classified as potentially hazardous asteroids (PHAs).

1, 2 and 3 are correct.

The Ring of Fire (also known as the Rim of Fire or the Circum-Pacific belt) is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur.
The Ring of Fire is a direct result of plate tectonics: the movement and collisions of lithospheric plates, especially subduction in the northern portion. It is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements.
It has more than 75% of the world’s active and dormant volcanoes. About 90% of the world’s earthquakes and about 81% of the world’s largest earthquakes occur along the Ring of Fire.

Doldrums, also called equatorial calms, equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator. The northeast and southeast trade winds meet there; this meeting causes air uplift and often produces clusters of convective thunderstorms. They occur along the Equator in the Indian and western Pacific oceans and slightly north of the Equator off the African and Central American west coasts.

None of the above is correct.

Fold mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges.
The Himalayan Mountains and the Alps are young fold mountains with rugged relief and high conical peaks.
The Appalachians in North America and the Ural Mountains in Russia have rounded features and low elevation.
They are very old fold mountains.
Block Mountains are created when large areas are broken and displaced vertically.

1 and 2 are correct.

Asafoetida, or heeng, is a common ingredient in most Indian kitchens.
• Heeng is not cultivated in India.
• India imports Rs 600 crore worth of this pungent flavoured herb every year.
• It is a perennial plant. The plant stores most of its nutrients inside its deep fleshy roots.
• Asafoetida is endemic to Iran and Afghanistan, the main global suppliers.
• It thrives in dry and cold desert conditions.
Scientists at CSIR-Institute of Himalayan Bioresource, Palampur (IHBT), are on a mission to grow heeng in the Indian Himalayas. The first sapling has been planted in Himachal Pradesh’s Kwaring village in Lahaul valley.
