For gate A, choose the statements that are valid: 

(a) The hydrostatic force acting on the gate increases as H increases.

(b) The distance between the CP on the gate and the centroid of the gate decreases as H increases. 

(c) The distance between the CP on the gate and the centroid of the gate remains constant as H increases. 

(d) The torque applied to the shaft to prevent the gate from turning must be increased as H increases. 

(e) The torque applied to the shaft to prevent the gate from turning remains constant as H increases.
