Hydraulic efficiency = Total head/ideal head.
So I think it should remain same.

Hydraulic efficiency = Q*H.
When Q increases and then H will decrease so here two opposite factor work together so practically it has seen that initially, hydraulic efficiency increase to a BEP and then decrease, so answer D is correct.

From the hydraulic efficiency of a centrifugal pump, it is clear that with increase of velocity the hydraulic efficiency will be decreased.

What is mean by monotonically?

As per centrifugal pump performance curve efficiency first increase with flow rate and after reaching the best efficiency point efficiency goes on decreasing, because any equipments, instruments and electrical designed and fabricated for maximum calibration value after that efficiency decreases.
