A-3, B-4, C-1, D-2

A-1, B-3, C-4, D-2

A-2, B-1, C-3, D-4

A-1, B-2, C-4, D-3

Solution:

Nutrient enrichment of the water bodies due to flow of the fertilizers causes the growth of algae and results in eutrophication.Sanitary landfill is one of the methods of waste disposal. This is the isolated areas where landfilling is done to ensure that the wastes do not interact with the environment.UV- B radiation causes snow blindness as it acts as an important factor in the induction of cataracts which causes permanent damage to the cornea.Jhum cultivation is a practice of cultivation and it involves clearing the land of trees and vegetation. The burnt soil contains potash which increases the nutrient content of the soil.Thus, the correct answer is option A.
