'The Wildlife Protection Act', 1972 is an act of the parliament of India enacted for protection of plants and animal species. Before 1972, India only had five designated national parks. Among other reforms, the act established schedules of protected plant and animal species; hunting or harvesting these species was largely outlawed. The act provides for the protection of wild animals, birds and plants; and for matters connected therewith or ancillary or incidental thereto. It extends to the whole of India, except the State of Jammu and Kashmir, which has its own wildlife act. It has six schedules, which give varying degrees of protection.
So, the correct answer is '1972'.
