The correct answer is option 1: Sanctuary. A sanctuary is an area that is specifically designated for the protection of wildlife. It is usually a large tract of land where human activity is restricted to maintain the natural habitat and ensure the safety of various species of animals and plants. Sanctuaries are established with the aim of preserving biodiversity and allowing the wildlife to thrive without interference. These areas provide a safe haven for animals, especially endangered species, and also offer opportunities for research, education, and tourism. It is important to note that while both national parks and sanctuaries focus on wildlife conservation, sanctuaries typically have stricter regulations and greater emphasis on protecting specific species or habitats. Thus, option 1, Sanctuary, is the correct answer for this question.
