Solution
The correct option is A the point of intersection of the inflow and outflow hydrographs When outflow from a reservoir is uncontrolled as in freely operating spillway, then the peak of outflow hydrograph will occur at a point of intersection of inflow and outflow curves, whereas if outflow from a reservoir is controlled, then peak will occur after the intersection of the curve.
