The correct answer is (d) shaft spillway

Easy explanation: A shaft spillway is generally adopted when the possibility of an overflow spillway and a trough spillway has been ruled out. The discharge does not increase at such a high rate as in weir type spills. Hence, it may not prove as useful as a weir type spills if unestimated high floods occur.
