Scientists believe that great apes such as chimpanzees and gorillas are more closely related to humans based on the evolutionary timeline because apes are larger than monkeys and have long legs and no tails. Apes are known to have larger brains than monkeys which makes them so closely related to us. This fact cancels out B and C for the answer. Also, apes (gorillas, orangutans, etc.) are much larger than monkeys (mandrill, lesula, etc.). This right away cancels out option D. What's left is option A which features body parts and comparisons that are comparatively accurate towards humans. Hope this helped :))
