Answer:

Correct Answer: A

Solution:

Carolus Linnaeus called humans as Homo sapiens or wise men and placed them along with apes and monkeys.

There are certain similarities between human and chimpanzee.

These are - (i) RNA content of diploid cells is similar.

(ii) DNA matching shows that human similarity is 100% with chimpanzee and (iii) Banding pattern of chromosomes shows very little difference in chromosomes 3 and 6 between humans and chimpanzee.

Thus it can be concluded that among the primates, chimpanzee is the closest relative of the present day humans.
