If a fire hose is left unattended and under pressure with the nozzle shut off, the fire hose will __________.

Correct Answer: Option C — remain motionless

Modern fire hoses are designed to withstand internal pressure without erratic movement when the nozzle is shut off. Provided the hose is properly laid out and secured, the internal pressure acts uniformly against the hose walls, keeping the hose stable and motionless while under operational pressure.
