Answer:
D) Medulla oblongata
Step-by-step explanation:
The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem.
It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing.
It connects the brain to the spinal cord.
