A reinforced masonry beam is designed to resist a given bending moment, using the allowable stress design method. If the effective depth is halved, while width and reinforcement are kept constant, the effect will be O (A) to halve the maximum compressive stress in the masonry O (B) insignificant O (C) to double the maximum compression stress in the masonry O (D) to quadruple the maximum compressive stress in the masonry
