Answer:
Option-C
Explanation:
Habitat fragmentation is a process during which large habitat is fragmented in smaller habitats by man-made activities. Habitat fragmentation is a very harmful process as it is one of the major factors for the loss of biodiversity in the ecosystem.
Due to division of the larger habitat into the smaller fragments, the population present in the smaller area are more susceptible to extinction as they will not interbreed with the individuals of the population stuck in another small habitat.
Thus, Option-C is correct.
