Answer:
The correct answer will be- Option-A
Explanation:
The Theory of Island Biogeography was proposed by the MacArthur and Wilson's in 1967 which proposed that the number of species-immigration and extinction rates are determined by the size of the island and distance of the island from the mainland.
The suggestions made by them are:
1. The islands which remain farther from the mainland receive very few species as compared to the closest mainland.
2. Smaller island shows a high rate of species extinction as compared to the larger island.
Thus, option-A is the correct answer.
