What is the role of national parks in wildlife conservation?

Correct answer: Giving legal protection to wildlife and their habitats

The direct answer is A: national parks give legal protection to wildlife and their habitats. Wildlife conservation means protecting animals, plants, and the places where they live so that populations can survive and reproduce. In a national park, laws restrict or prohibit activities such as hunting, habitat destruction and uncontrolled resource use. Protection of habitat is essential because animals need food, water, shelter and breeding areas, not merely safety from hunters. Option A correctly states this central role. Option B is wrong because illegal hunting harms wildlife and is prohibited, not encouraged. Option C is wrong because converting forests into cities destroys habitats and reduces biodiversity. Option D is wrong because polluting rivers damages water quality and aquatic as well as land ecosystems. National parks do not solve every conservation problem by themselves, but their legal protection creates a strong foundation for conservation. Memory cue: national park means protected wildlife plus protected habitat.
