Answer:

Option D

Explanation:

Increase in organic matter in the water will lead to production of microbes, algae, and all other water species by feeding on increased organic matter. This organic matter will act as food for the species living under the water.

With increased food supply, the population of water species will also increase which in turn will consume more and more dissolved oxygen from water thereby making it devoid of oxygen.
