The reciprocating pump creates a suction effect when there is a
Direct Answer
Option A: decrease in pressure
Reciprocating pumps operate by creating a pressure differential. As the piston retracts, it increases the volume within the cylinder, thereby decreasing the local pressure. This lower pressure allows the surrounding liquid to flow into the cylinder, initiating the suction stroke as per pump principles.
