Question

Assertion (A): The human ear is responsible for hearing, dynamic equilibrium and also static balance.

Reason (R): Cochlea, semi-circular canals and vestibule (utriculus and sacculus) are responsible for hearing, dynamic balance and static balance respectively.

1. A is True and R is False.
2. A is False and R is True.
3. Both A and R are True.
4. Both A and R are False.

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(3)

Explanation:

The human ear performs three important functions: hearing, maintenance of dynamic equilibrium, and maintenance of static balance. Therefore, the Assertion (A) is true.

The cochlea is responsible for hearing, the semicircular canals help maintain dynamic balance during head movements, and the vestibule containing the utriculus and sacculus helps maintain static balance. Therefore, the reason (R) is also true.

Hence, both A and R are true.
