Answer 1

the best answer would be A.

Answer 2

Option (A)

Step-by-step explanation:

Eutrophication usually refers to the condition when there are excessive nutrients present in the water body. These nutrients are frequently accumulated in the water body from the flowing down of materials from the land areas. This leads to the decreasing amount of dissolved oxygen in the water as a result of which the lives existing in the water body such as the aquatic plants and marine animals find difficult to survive and thereby leads to their deaths.

Thus, the correct answer is option (A).
