Answer:

The answer is A

Explanation:

Eutrophication is a natural process that a lake goes through over hundreds to thousands of years. Natural eutrophication is also sometimes referred to as lake aging. The additional nutrients cause algal blooms, additional plant growth and overall poor water quality, making the lake less suitable for recreation.
