D. Chimpanzee

Answer 1

Hint: Humans and apes are different from other primates as both of them lack tails, have more learned behavior patterns and intelligence. Both of them belong to Hominoidea and are referred to as hominoids.

Complete answer: Gibbons are the smallest apes and are also known as lesser apes. They walk bipedally and show sexual dimorphism. They have long arms, short legs, permanently curved fingers, and lightweight bodies.
Orangutans are rarest Asian apes that are large in size and show marked sexual dimorphism. They walk quadrupedally and reddish brown hairs on the body but hairless face. They are vegetarians and intelligent animals.
Gorillas are the largest apes and are found in Africa. They are terrestrial animals with Stout and muscular bodies and massive heads covered with thick muscles. They are shy, peaceful, vegetarians and knuckle walkers. They show sexual dimorphism. They have great adaptive features that help them in their survival in forests. The genetic code of humans and gorillas are approximately 98.3% the same and they also show emotions like humans. They have hairless faces with small eyes, broad chests and shoulders.
Chimpanzees are the most closely related to humans among all other apes. They are tall and less muscular and walk quadrupedally. They are intelligent and peaceful animals.
So among all these, the largest ape is Gorilla.
So, the correct answer is “Option C”.

Note: The earliest and primitive ape lived about 40 million years ago in the Oligocene period and is known as Parapithecus. It is believed to represent an ancestral stock from which all Hominoids have been derived. Proconsul is believed to be an ancestor of the modern chimpanzee.
