The correct choice is (b) chute spillway

To elaborate: Straight drop spillway is a low weir and simple vertical fall type structure which may be constructed on thin arch dams or small bunds etc. An ogee spillway is most suitable for concrete gravity dams. Chute spillway can be provided easily on earth and rock-fill dams.
