D
cranial nerve III
Explanation: 

Detailed explanation-1: -Inside the inner ear, the cochlea gathers information about sound. The vestibular organs gather information about motion and changes in space. These all help to create a sense of balance. The eighth cranial nerve sends all of this information from the inner ear to the brain.

Detailed explanation-2: -To quickly assess the auditory component, a simple test is done with the patient in sitting position. Cover one of the patient’s ears at a time. At around 60cm distance of the open ear whisper a couple of numbers at the end of exhalation and ask the patient to repeat them. Repeat the procedure with the other ear.

Detailed explanation-3: -Vestibulocochlear Nerve (Cranial Nerve VIII) The balance organs are contained in the labyrinth, and there are two types: the semicircular canals, which sense angular head movement, and the otoliths (utricle and saccule), which sense gravity and linear motion.
