Explanation:
The question you're asking about concerns the pump pressure required for relay pumping, which is a term typically used in firefighting when water is pumped through a series of pumps from a water source to the fire scene. The standard pump pressure often suggested for relay pumping is 20 PSI (pounds per square inch). This additional pressure is to compensate for friction loss in the hoses, ensuring a reliable and constant water supply during the relay operation.The correct multiple-choice option is (a).
