Answer:

The correct option is;

D. A population of moose living at the base of a volcano is nearly wiped out when the volcano erupts

Step-by-step explanation:

Genetic drift is the altering in the number of occurrence of a variant of an already existing gene within a small population due to disappearance by chance of genes of individuals as they fail to reproduce or survive

Genetic drift is said to have occurred in a population where, over time, there is a frequency change of a particular allele

Therefore, the scenario that will most likely result in a genetic drift is that where the population of moose living at the base of a volcano is nearly wiped out when the volcano erupts because there is a definite reduction in the different variant gene pool which will reflect in the frequency of the genes in the next generation of offspring
