Solution
The correct option is C Hypothalamus
The hypothalamus is a mass of grey matter present at the base of the cerebrum. The center for thirst and drinking regulation is present in lateral hypothalamus while that for hunger and satiety is present in the arcuate nucleus, ventral nucleus and lateral hypothalamic area. This makes option B correct. The two cerebral hemispheres are divided into four lobes which are the centers of motor, sensory and association activities. This makes option A incorrect. Cerebellum serves to coordinate the voluntary movements of skeletal muscles as well as posture, balance and equilibrium. Option C is incorrect. Medulla oblongata consists of reflex centers that control heartbeat, blood vessel diameter and rhythm of breathing as well as other vital functions. Option D is incorrect. Therefore, the correct answer is option B.
