Cargo hose carried on tank vessels must be designed to withstand the pressure of the shutoff head of the cargo pump or pump relief valve setting, but in no case should it be less than __________.

Correct Answer: Option B — 150 psi

Per 46 CFR 35.35-20, cargo hoses must be designed to withstand the maximum pressure of the pump's shutoff head or the relief valve setting. Regardless of these calculations, the regulation mandates a minimum burst pressure rating of 150 psi to ensure structural integrity during high-pressure cargo transfer operations.
