The Correct Option is A
Solution and Explanation
Sewall Green Wright was an American geneticist known for his influential work on evolutionary theory. The theory of random genetic drift was proposed by him. Genetic drift or allelic drift is the change in the frequency of a gene variant (allele) in a population due to random sampling. The effect of genetic drift is larger in small populations, and smaller in large populations.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
