Answer:
The correct answer will be option-C.
Step-by-step explanation:
The race is a term used to denote the group of people who share common ancestors and descended from it. The groups are based on the physical appearance and social qualities as a result of adaptation and natural selection which led to the variation in the species of humans.
Although humans show variation, they all belong to the same species and same genus- Homo sapiens. The sapiens share 99% DNA as well they can successfully reproduce with each other which shows that they have descended from a common ancestor.
Thus, Option-C is the correct answer.
