Solution

The correct option is C Assertion is correct but Reason is incorrect.
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
Hence, According to Hardy-Weinberg Equilibrium, the frequency of an allele remains the same generation after generation.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.
For instance, mutations disrupt the equilibrium of allele frequencies by introducing new alleles into a population.
Hence, The only way to bring about a change is not by natural selection.
So, the correct answer is 'Assertion is correct, but Reason is incorrect'.
