The correct option is (B) Changes in allele frequencies in a population occur over generations.

Microevolutions occur when changes in allele frequencies in a population occur over generations.

What is Microevolution?

Microevolution is the gradual shift in allele frequencies within a population. Four separate processes—mutation, natural and artificial selection, gene flow, and genetic drift—are responsible for this shift.
Compared to the changes referred to as macroevolution, this transformation occurs over a very brief period of time (in evolutionary terms).
Microevolution via natural selection is demonstrated by the resistance to pesticides, herbicides, and antibiotics.
