Consider the following statements : 1. Animal Welfare Board of India is established under the Environment (Protection) Act, 1986. 2. National Tiger Conservation Authority is a statutory body. 3. National Ganga River Basin Authority is chaired by the Prime Minister. Which of the statements given above is/are correct?

Let's evaluate each statement regarding various environmental/conservation bodies in India:

1. Animal Welfare Board of India is established under the Environment (Protection) Act, 1986. This statement is incorrect. The Animal Welfare Board of India (AWBI) is a statutory advisory body established under Section 4 of The Prevention of Cruelty to Animals Act, 1960, not the Environment (Protection) Act, 1986. Its primary function is to advise the government on animal welfare issues and enforce the Prevention of Cruelty to Animals Act.

2. National Tiger Conservation Authority is a statutory body. This statement is correct. The National Tiger Conservation Authority (NTCA) is a statutory body constituted under the enabling provisions of the Wildlife (Protection) Act, 1972 (amended in 2006) for strengthening tiger conservation.

3. National Ganga River Basin Authority is chaired by the Prime Minister. This statement is correct. The National Ganga River Basin Authority (NGRBA) was constituted in 2009 under the Environment (Protection) Act, 1986, and was indeed chaired by the Prime Minister of India. Its objective was to ensure abatement of pollution and conservation of the river Ganga. (Note: NGRBA was later replaced by the National Council for Rejuvenation, Protection and Management of River Ganga, known as National Ganga Council, which is also chaired by the Prime Minister).

Therefore, statements 2 and 3 are correct.
