Answer:
The correct answer will be option- connect two otherwise isolated populations
Explanation:
Habitat corridors also are known as wildlife corridors refers to the area or habitat which connects the wildlife population separated by human activities which leads to habitat fragmentation.
The habitat fragmentation directly causes genetic defects in wildlife population due to inbreeding. This could also lead to reduction or extinction of the wildlife population.
So, to overcome the problems of habitat fragmentation, attempts were made which resulted in the making of green corridors or wildlife corridors which connects or allow the movements of isolated population which help them promote genetic diversity.
Thus, the selected option is the correct answer.
