Statement 1 is incorrect. The Animal Welfare Board of India (AWBI) is established under Section 4 of the Prevention of Cruelty to Animals Act, 1960, not the Environment (Protection) Act, 1986. Statement 2 is correct. The National Tiger Conservation Authority (NTCA) is a statutory body constituted under Section 38L(1) of the Wild Life (Protection) Act, 1972, as amended in 2006. Statement 3 is correct. The National Ganga River Basin Authority (NGRBA) was indeed chaired by the Prime Minister of India. This authority was constituted in 2009 under the Environment (Protection) Act, 1986. (Note: NGRBA was later replaced by the National Council for Rejuvenation, Protection and Management of River Ganga (National Ganga Council) in 2016, which is also chaired by the Prime Minister).
