Correct choice is (a) highly variable discharge

Explanation: A steep slope represents a stream with highly variable discharge and a flat slope represents a small variability of flow. The considerable base flow is indicated by a flat portion on the lower end of the curve and the upper end of the curve is of river basins having large flood plains.
