A) cochlear duct.
B) outer ear.
C) middle ear.
D) ampullae.
E) cochlea (organ of Corti) .
Rotational Equilibrium
Maintenance of balance when the head and body are suddenly moved or rotated.
Ampullae
Small bulbous structures, especially in the context of the ampullae of Lorenzini in sharks, sensing electric fields and temperature.
Cochlear Duct
A spiral-shaped cavity within the cochlea of the inner ear, filled with fluid and containing the organ of Corti, which produces nerve impulses in response to sound vibrations.

Final Answer :
D
Explanation :
The sense of rotational equilibrium is accomplished by hair cells found in the ampullae, which are located in the semicircular canals of the inner ear. The hair cells are stimulated by the movement of fluid that occurs when the head moves, allowing us to sense rotational motion and maintain our balance. The cochlear duct, outer ear, middle ear, and cochlea (organ of Corti) are all involved in hearing, not balance.
