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

A fire hose under pressure with a closed nozzle remains stable because the internal forces are balanced. The pressure exerts equal force in all directions against the hose walls. Violent movement or 'lashing' typically occurs only when the nozzle is open and the reaction force of the water stream is not properly controlled.
