Consider the following statements : 1. The boundaries of a National Park are defined by legislation. 2. A Biosphere Reserve is declared to conserve a few specific species of flora and fauna. 3. In a Wildlife Sanctuary, limited biotic interference is permitted. Which of the statements given above is/are correct?

1. Statement 1: The boundaries of a National Park are clearly demarcated and established by legislation (state or central government notification under the Wildlife Protection Act, 1972). Alteration of boundaries also requires legislative action. This statement is correct. 2. Statement 2: A Biosphere Reserve is a large area designated to conserve biodiversity in its totality (ecosystems, species, and genetic resources). It is not focused on just a few specific species of flora and fauna but aims for the conservation of the entire ecosystem and its sustainable use. This statement is incorrect. 3. Statement 3: In a Wildlife Sanctuary, certain human activities may be allowed to a limited extent (regulated grazing, collection of minor forest produce for local communities) as long as they do not adversely affect wildlife. This constitutes limited biotic interference, unlike National Parks where most human activities are prohibited. This statement is correct. 4. Since statements 1 and 3 are correct, option (C) is the answer.
