D) If both the assertion and reason are false
E) If the assertion is false but reason is true
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.
