The correct answer is the 5th cranial nerve. The 5th cranial nerve, also known as the trigeminal nerve, is responsible for controlling chewing in the human body. This nerve is one of the largest cranial nerves and is responsible for sensations in the face, as well as the motor functions involved in chewing.

Options B, C, and D are incorrect because they do not have the primary role in controlling chewing. The 6th cranial nerve is responsible for controlling eye movement, the 7th cranial nerve controls facial expressions and taste on the anterior two-thirds of the tongue, and the 8th cranial nerve is responsible for hearing and balance.
