The correct option is (c) reservoir

Easy explanation: The reservoir itself acts as a forebay when it is constructed by building a dam. The water is taken to the powerhouse directly from the reservoir through penstocks. Following are some functions of forebay:

• To temporarily store water and to meet the instantaneous demand

• Absorbs the short interval variations and fluctuations.
