The scenario that will decrease the genetic variation of a population is a population of birds suddenly decreasing their frequency of procreation.

What do you mean by Genetic variation?

Genetic variations may be defined as the presence of differences in sequences of genes between individual organisms of a species.

Mutations always lead to an increase in the genetic diversity among individuals. While decreasing the rate of crossbreading may decline the rate of genetic diversity.

Therefore, the scenario that will decrease the genetic variation of a population is a population of birds suddenly decreasing their frequency of gender reproduction. So, the correct option is B.
