The correct response that most accurately describes the difference between a limited war and a total war is:
Limited war does not target civilians or infrastructure because the invading force is planning to keep the land they conquer. With a total war, those limits do not exist because the goal is destruction of the enemy.
This answer captures the fundamental distinction between the two types of warfare: limited war is constrained in its objectives and methods, while total war is characterized by an all-encompassing approach aimed at the complete defeat of the enemy, with fewer restrictions on targets.
