Solution

The correct option is D Discontinuous variations
Darwin in his 'Natural selection Theory' did not believe in any role of discontinuous variation. Darwin believed in continuous variation, for example, Darwin's finches, vary continuously: every individual in the population differs slightly from every other individual. Discontinuous variation is controlled by alleles of a single gene or a small number of genes. The environment has little effect on this type of variation. For example blood groups.
