• B. Vagus
• C. Optic nerve
• D. None of the above

Answer 1

Answer: (C)

Optic nerve

Sensory nerves are the nerves which carry the stimulus from the organs to the brain for its interpretation. The optic nerve is a second cranial nerve which originates from the retina of the eye and carries the stimulus to the occipital lobe of the cerebrum which interprets the information. The right optic nerve originates from the retina of the right eye while the left optic nerve arises from the retina of the left eye. The two optic nerve intersect each other below the hypothalamus forming the optic chiasma and interchange the path. The right optic nerve moves to the left occipital lobe and the left optic nerve moves to the right occipital lobe.

So, the correct answer is option C.
