The answer is; D.

Each of the two hemispheres of the brain controls the movement of the muscles of the opposite side of the body, that is, the left hemisphere controls the right side muscles and vice versa. For the two hemispheres to work together, they have to communicate and the corpus callosum, which sits at the center of the two halves, provided this connection.
