The correct option is D Gorilla
Gorillas are blessed with the ability to show emotions like humans. Their adaptive features help them to survive in the forest. The brain size of gorillas averages 500 cc, but males, being bigger, tend to have larger brains than females. Various sources list the maximum brain size of gorillas as 650 cc, 700 cc, or in the case of one exceptional specimen, 752 cc. Chimpanzees have a brain size between 300 and 500 cc, with an average of 400 cc. Brain size estimates suggest that the brain of Homo sapiens was larger than in other hominin species. The average cranial capacity of Homo sapiens is roughly 1300 cubic centimeters, making the brains of this species absolutely smaller than those of Homo neanderthalensis. The cranial capacity for Cro-Magnon man is 1,590 cc. Thus, option D is correct.
