Solution

The correct option is C It has few hereditary variation that can be seen with high power microscope
Drosophila melanogaster completes it's life cycle in about two weeks and produces large number of progenies from single mating. Clear differentiation of sexes is found with many types of hereditary variations which can be seen with low power microscope. Because of these reasons, Morgan carried out his experiment on Drosophila melanogaster.
