Optimum yield of a well is arrived at by conducting a “step drawdown test” in the well. Arrange the steps in sequence for conducting a "step drawdown test" from the below statements.
A. Bore is first pumped at a very low and constant discharge rate for a fixed period of time in such a manner that the water level stabilizes at a shallow depth.
B. The pump discharge is then increased to a medium rate of pumping so that water level falls further down but eventually stabilized at an intermediate depth.
C. The pump discharge is further increased higher so that the water level again stabilizes at a lower level further down.
D. When the discharge versus steady state drawdown of the different steps is plotted, a parabolic curve is obtained.

Given below are two statements:
Statement I: In pumping test, the water level in the well is depressed to an amount equal to the safe working head for the subsoil.
