Answer:
B. Midbrain
Explanation:
The midbrain is the uppermost region of the brainstem, which serves as the primary connection between the central nervous system. The midbrain is made up of three major components: the colliculus, tegmentus, and cerebral peduncles. The midbrain, commonly known as the roof and the tegmentum, is a growing human brain structure that includes the roof and the tegmentum. The midbrain is necessary for muscle movement, particularly eye movement, as well as multisensory processing.
