Human ear converts audible frequencies of sound into electric signals which travel to the brain through-

Correct option is A

The correct answer is (a) Auditory nerve.
· The auditory nerve is responsible for transmitting the electrical signals generated by the ear to the brain. When sound waves enter the ear, they are converted into mechanical vibrations by the eardrum and then into electrical signals by the cochlea in the inner ear.
· These electrical signals are then carried to the brain through the auditory nerve, where they are interpreted as sound.
Information Booster:
· The auditory nerve, also known as the cochlear nerve, is part of the vestibulocochlear nerve (cranial nerve VIII) and plays a crucial role in hearing.
· It carries information about the pitch, volume, and duration of sounds to the auditory cortex of the brain.
· Damage to the auditory nerve can result in sensorineural hearing loss, impacting the ability to perceive sound accurately.
Explanation of Other Options:
· Olfactory nerve: This nerve is responsible for the sense of smell, not hearing.
· Trochlear nerve: This nerve controls eye movement and has no connection to hearing.
· Optic nerve: This nerve transmits visual information from the retina to the brain and is associated with vision, not hearing.
