Right answer is (d) M15

To elaborate: The mixture ratio of M15 grade is 1:2:4 (cement, sand, coarse aggregate) and this ratio is a good quality type for construction of cement concrete lining. This lining gives satisfactory service, high durability, hydraulic efficiency, weed free surface, long life, minimum maintenance cost.
