Answer:

The answer is D.

Explanation:

The example given in the question is an example of gene flow which can be described as the movement of specific genes from the the gene pool population to population.

The act of catching the bigger fish and letting the smaller ones escape is changing the gene pool of the North East Arctic Cod and causing the next generations to have smaller and smaller sizes which is given as the genetic variation decrease due to gene flow.

I hope this answer helps.
