Answer:

Stabilizing Variation.

Explanation:

This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.

Organisms with varied or specific  traits within the population are selected against by the selection pressure,  with little chances of reproduction, while organisms in between, ( with least variation of  this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives  rise to narrow population  of these  particular organisms,(stabilizing variation) which are therefore naturally selected.

Therefore, the variation of the organisms in this population is kept  close to the  centre of  the same  mean value.

Mutagen on the other hand are agents which cause mutations which means alterations in the DNA of organisms. It affects the transcription and replication of the DNA thereby leading to cell death and other effects such as diseased condition.

This is therefore the reason why option D was chosen as the most appropriate choice.
