Answer: a) pons
Step-by-step explanation:
The pons is a part of the brainstem in humans and other bipeds. It lies in between the midbrain and medulla oblongata.
This region of the brainstem involves the neural pathways that tracts and conducts the signals from the brain down to the cerebellum and medulla. The pons is a control center for breathing. It is involved in the sensation of taste, balance, and hearing. It also regulates deep sleep.
