Answer

B

Explanation

Vestibular apparatus of membranous labyrinth is an intricate series of interconnected and fluid filled canals, which regulates balances and spatial orientation in the absence of vision. Thus, the movement of body will be regulated only by vestibular apparatus.
The otolith organs (utricle and saccule) regulate linear acceleration and semicircular canals sense rotational accleration in various directions.
The cochlea, tectorial membrane and organ of Corti are responsible for transduction of sound waves.
