Organizing sensory input that guides movement is a function of the
a. cerebellum
b. pons
c. medulla
d. brainstem

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.

i believe the answer would be 'd'.

hope this !
