Final Answer :
B
Explanation :
The ventral root of a spinal nerve contains motor (efferent) fibers that are responsible for movement. Cutting it would lead to a loss of movement in the regions innervated by that nerve, but sensation, including pain, would not be affected because it is carried by the dorsal root.
