Best answer
Right choice is (d) Eutrophication

Explanation: Eutrophication is the process that leads to the killing of aquatic life due to the depletion of oxygen because of the excessive growth of algae due to the over-abundance of phosphorous in the coastal areas. Eutrophication is also known as hypertrophication and is the result of an increase in minerals in a water body.
