Statement 2 is correct.

The resignation letter is submitted to the President, and not the Chief Minister.
A governor holds office for a term of five years from the date on which he enters upon his office. However, this term of five years is subject to the pleasure of the President.
The Supreme Court held that the pleasure of the President is not justifiable. The governor has no security of tenure and no fixed term of office. He may be removed by the President at any time without mentioning any grounds for his removal.

Only 3 is correct.

Article 157 and Article 158 of the Constitution of India specify eligibility requirements for the post of governor. They are as follows:
A governor must:
• be a [citizen of India].
• be at least 35 years of age.
• not be a member of the either house of the parliament or house of the state legislature.
• not hold any office of profit.
Additionally, two conventions have also developed over the years.
First, he should be an outsider, that is, he should not belong to the state where he is appointed, so that he is free from the local politics.
Second, while appointing the governor, the president is required to consult the chief minister of the state concerned, so that the smooth functioning of the constitutional machinery in the state is ensured. However, both the conventions have been violated in some of the cases.

Only statement 1 is correct.

When a bill is sent to the governor after it is passed by state legislature, he can:
(a) Give his assent to the bill, or
(b) Withhold his assent to the bill, or
(c) Return the bill (if it is not a money bill) for reconsideration of the state legislature. However, if the bill is passed again by the state legislature with or without amendments, the governor has to give his assent to the bill, or
(d) Reserve the bill for the consideration of the president. In one case such reservation is obligatory, that is, where the bill passed by the state legislature endangers the position of the state high court. In addition, the governor can also reserve the bill if it is of the following nature:
(i) Ultra-vires, that is, against the provisions of the Constitution.
(ii) Opposed to the Directive Principles of State Policy.
(iii) Against the larger interest of the country.
(iv) Of grave national importance.
(v) Dealing with compulsory acquisition of property under Article 31A of the Constitution.

Both 1 and 2 are incorrect.

The governor is neither directly elected by the people nor indirectly elected by a specially constituted electoral college as is the case with the president. He is appointed by the president by warrant under his hand and seal.
As held by the Supreme Court in 1979, the office of governor of a state is not an employment under the Central government. It is an independent constitutional office and is not under the control of or subordinate to the Central government.

All of the above are correct.

In India, the practice of the President addressing Parliament can be traced back to the Government of India Act of 1919. This law gave the Governor-General the right of addressing the Legislative Assembly and the Council of State. The law did not have a provision for a joint address but the Governor-General did address the Assembly and the Council together on multiple occasions. There was no address by him to the Constituent Assembly (Legislative) from 1947 to 1950. And after the Constitution came into force, President Rajendra Prasad addressed members of Lok Sabha and Rajya Sabha for the first time on January 31, 1950.

The President’s address is one of the most solemn occasions in the Parliamentary calendar. It is the only occasion in the year when the entire Parliament, i.e. the President, Lok Sabha, and Rajya Sabha come together.
