The correct answer is option 3, National Park. A National Park is an area that is reserved specifically for the protection and conservation of wildlife and their habitats. It is usually a large area of land that is managed by the government or a designated authority. National Parks are established to preserve the natural environment and biodiversity while allowing visitors to appreciate and learn about the wildlife and ecosystems. They often have strict regulations and rules to ensure the conservation of the wildlife and to maintain the ecological balance. On the other hand, option 1, Sanctuary, refers to an area where specific species are protected and can reproduce freely without any disturbance from human activities. Option 2, Forest, refers to a large area of land covered with trees and vegetation. Option 4, Botanical garden, is a controlled environment where plants, including rare and endangered species, are cultivated for research, conservation, and public display.
