The correct option is B Both A and R are true but R is not the correct explanation of A

Ears are responsible for the equilibrium and posture of our body. The inner ear consists of three semicircular canals that contains a fluid called endolymph. This fluid moves in the same direction as our head. After getting down from the roller coaster the fluid in our ears is still in motion due to the property of inertia sending false signals to the brain that the body is still in motion. Therefore, making us feel dizzy and lose our balance.
