Answer and Explanation:
The correct answer is (b) 2 only
It is the Governor of the State who recognizes and declares any community of that State as a Scheduled Tribe: Incorrect. The power to recognize and declare a community as a Scheduled Tribe is vested in the President of India under Article 342 of the Indian Constitution. The President issues a notification specifying the Scheduled Tribes in relation to that State or Union Territory, which is then subject to parliamentary amendment.
A community declared as a Scheduled Tribe in a State need not be so in another State: Correct. The status of a community as a Scheduled Tribe is specific to a State or Union Territory. Therefore, a community declared as a Scheduled Tribe in one State may not necessarily be recognized as such in another State.
Therefore, only statement 2 is correct, making option (b) the right answer.
