Answer: The correct option is A (ventral ramus).

Explanation: Damage to ventral ramus branch of the spinal nerve is likely only to have an effect on the muscles of the limbs. The ventral ramus is the anterior division of a spinal nerve. The ventral rami supply the antero-lateral parts of the trunk and the limbs. Therefore the lbs would be affected if damage occurs at the ventral ramus.
