• B. 3, 4 and 6
• C. 2, 3 and 5
• D. 5, 8 and 9

Answer 1

Answer: (B)

3, 4 and 6

The seventh cranial nerve is the facial nerve that control taste buds, facial muscles and glands (tear and salivary). Oculomotor (3), trochlear (4) and abducens (6) nerves are the motor nerves that carry nerve impulse from midbrain and pons to eye muscles and regulate their movement. Optic (2) and trigeminal (5) regulate retina and eyes respectively. Vestibulocochlear (8) and glossopharyngeal (9) nerves regulate inner ear and pharynx respectively. Thus, the correct answer is option B.
