Answer:

The correct option is D: Right primary motor cortex

Explanation:

The primary motor cortex of the brain is the part of the brain that is involved that controls movement and is involved in motor functions. It is usually located in the brain's frontal lobe. The primary motor cortex generates neural impulses which helps in controlling movement execution. The primary motor cortex has a left and right cerebral hemisphere which controls the movement in the contralateral side of the body. This means that the right primary motor cortex controls movement on the left side of the body and the left primary motor cortex controls movement on the right side of the body.
