• A. Medulla oblongata
• B. Pons
• C. Cerebellum

The correct option is D Hypothalamus

Hypothalamus is mass of grey matter present at the base of the cerebrum. The centre 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. The anterior hypothalamic region regulates body temperature. This makes option D correct.
Cerebellum serves to coordinate the voluntary movements of skeletal muscles as well as posture, balance and equilibrium.

Pons verolli is part of brain stem serves as the connector between spinal cord and brain and between different parts of the brain; it also controls breathing.
