Solution
The correct option is B Nutrient enrichment/eutrophication
Eutrophication is the natural aging of a lake by nutrient enrichment of its water. With time, streams draining the sewage pollutants and fertilizers into the lake introduce nutrients such as nitrogen and phosphorus, which encourage the growth of aquatic organisms. As the lake's fertility increases, algal bloom occurs. Algal bloom causes the deterioration of water quality and fish mortality and dead remains begin to be deposited on the lake bottom. Over the year, the lake is finally converted into the land. Thus, the correct answer is option B.
