Located in the hindbrain, this structure is responsible for coordinated movement and balance
A
cerebellum
B
brainstem
C
pons
D
medulla
Explanation: 

Detailed explanation-1: -The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. The cerebellum is the part of the brain that is responsible for coordinating voluntary movements.

Detailed explanation-2: -D. Cerebellum. Reason: The cerebellum is a part of the hindbrain, also known as the rhombencephalon. Its functions include controls of balance, coordination, and fine muscle control (e.g., walking). It also functions to maintain posture and equilibrium.

Detailed explanation-3: -There are three functional areas of the cerebellum – the cerebrocerebellum, the spinocerebellum and the vestibulocerebellum. Cerebrocerebellum – the largest division, formed by the lateral hemispheres. It is involved in planning movements and motor learning.

Detailed explanation-4: -The hindbrain (developmentally derived from the rhombencephalon) is one of the three major regions of our brains, located at the lower back part of the brain. It includes most of the brainstem and a dense coral-shaped structure called the cerebellum.

Detailed explanation-5: -Cerebrocerebellum – this is the largest area of the cerebellum, responsible for planning movements and motor learning. It also works to regulate coordination of muscle activation as well as eye movements.
