As flow decreases pressure will blank provided pump speed remains consistent.

Explanation:
When a pump runs at a fixed speed, the pressure it develops is higher at lower flow. This follows the pump’s head–flow behavior: as flow decreases, the pump can deliver more head (pressure) up to its shut-off head. So if flow is reduced while speed stays the same, the discharge pressure increases until the pump head and system head balance. The other options don’t fit because pressure does not stay the same, decrease, or fluctuate in a steady, fixed-speed scenario with reduced flow.
