A
brain stem
B
cerebrum
C
cerebellum
D
None of the above
Explanation: 

Detailed explanation-1: -Your cerebellum is a part of your brain located at the back of your head, just above and behind where your spinal cord connects to your brain itself. The name “cerebellum” comes from Latin and means “little brain.” For centuries, scientists believed your cerebellum’s job was to coordinate your muscle movements.

Detailed explanation-2: -The flocculonodular lobe. It is the oldest part of the brain in evolutionary terms (archicerebellum) and participates mainly in balance and spatial orientation. Its primary connections are with the vestibular nuclei, although it also receives visual and other sensory input.

Detailed explanation-3: -The cerebellum is important for making postural adjustments in order to maintain balance. Through its input from vestibular receptors and proprioceptors, it modulates commands to motor neurons to compensate for shifts in body position or changes in load upon muscles.
