Here are the essential concepts you must grasp in order to answer the question correctly.
Cochlear Duct and Cupula
The cochlear duct is part of the cochlea in the inner ear, responsible for hearing, while the cupula is a structure found in the ampulla of the semicircular canals, involved in balance. Therefore, pairing the cochlear duct with the cupula is incorrect, as they serve different functions and are located in different parts of the ear.

Vestibule and Macula
The vestibule is a central part of the inner ear that contains the macula, which is responsible for detecting linear acceleration and head position relative to gravity. This pairing is correct, as the macula is indeed located within the vestibule, specifically in the utricle and saccule.

Ampulla and Otoliths
The ampulla is a structure located at the base of each semicircular canal, containing the cupula and sensory hair cells for detecting rotational movements. Otoliths, on the other hand, are small calcium carbonate crystals found in the utricle and saccule of the vestibule, not in the ampulla. Thus, this pairing is incorrect.
