The correct option is A Optic lobes
The midbrain is also known as mesencephalon, the smallest region of the brain which connects the hindbrain and forebrain. It is associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation. Structures which are located in this region include Optic lobes (a lobe in the midbrain from which the optic nerve partly arises), cerebral peduncle, Tectum, Tegmentum etc. Hence, option A is correct.
