Answer:
C
Solution:
In human eyes, cornea absorbs UV B radiation, and causes inflammation of cornea, called snow-blindness. Biodegradble organic matter increases BOD of water, and non biodegradable substance like DDT gets accumulated in successive trophic levels of food chain leading to biomagnifications. Phosphate is plant nutrient which results in eutrophication.
