Answer
Answer:
A. The respiratory center, B. The vasomotor center, E. The cardiac center
Brief Explanations:
The medulla oblongata contains the respiratory center which controls breathing, the vasomotor center which regulates blood - vessel diameter and blood pressure, and the cardiac center which regulates heart rate. The auditory reflex center is mainly in the mid - brain, and the substantia nigra is in the mid - brain, not in the medulla oblongata.
