- C. Medulla oblongata

Explanation
The medulla oblongata is the lowermost part of the brainstem, and it is responsible for regulating vital functions such as breathing, heart rate, blood pressure, and digestion. It also serves as a pathway for nerve fibers traveling between the spinal cord and higher brain centers. The medulla oblongata gradually transforms into the spinal cord at the base of the brain.
