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 (A) to halve the maximum compressive stress in the masonry (B) insignificant (C) to double the maximum compression stress in the masonry (D) to quadruple the maximum compressive stress in the masonry
