The wooden plug inserted in the vent of a damaged tank of a MODU should be removed in case it is decided to __________.

Correct Answer: Option C — pump from the damaged tank

Vents must remain open during pumping operations to prevent the creation of a vacuum within the tank. If a tank is sealed with a plug, the pump will be unable to draw liquid, potentially causing structural damage to the tank or cavitation and failure of the pumping equipment.
