Answer:
Point D
Explanation:
Point D is the point that is most likely to not have any plants growing in it. The reason why this point of the body of water will not have any plants is because of the lack of light.

If there isn't any light, the plants can not perform photosynthesis, thus they can not produce their own food, which in turn means that they will not exist in such a place.
