a
b

d

Explanation:

Identify the anatomical location of the vestibular system

The vestibular system, which is responsible for balance and spatial orientation, is located in the inner ear. The inner ear structures (semicircular canals and otolith organs) and the vestibulocochlear nerve (cranial nerve VIII) are part of the peripheral nervous system.

Classify the type of vestibular disorder

A dysfunction of the vestibular system located in the inner ear or the vestibular nerve is classified as a peripheral vestibular disorder. In contrast, a central vestibular disorder involves the brainstem or cerebellum.

Match with the given options

Since the question refers to a dysfunction of the nervous system that processes balance (the inner ear/nerve structures), it is classified as a peripheral vestibular disorder, which corresponds to option B.

Answer:

• A. upper
• B. peripheral (Correct answer)
• C. lower
• D. central
