Right option is (b) Eutrophication
 
The explanation: The excessive richness of nutrients (phosphorus, nitrates, and detergents) in a lake or other body of water that leads to acceleration in the growth of algae and the natural aging of the lake is known as eutrophication. Excess algal growth deoxygenates water leading to the death of aquatic life.
