The fitting at the end of a cargo line in a tank that allows suction to be taken close to the bottom of a tank is a _______________.

A vacuum valve
B bell-mouth
C strainer
D suction end
AI Explanation

The correct answer is B) bell-mouth. A bell-mouth fitting is a specific type of fitting used at the end of a cargo line in a tank. It has a flared or bell-shaped opening that allows suction to be taken from close to the bottom of the tank, ensuring the maximum amount of cargo can be withdrawn. This design helps prevent the intake of sediment or sludge that may have settled on the tank bottom. The other options are incorrect because: A) a vacuum valve is used to control airflow, not to provide suction; C) a strainer is used to filter out debris, not specifically designed for bottom suction; and D) "suction end" is a generic term, not a specific type of fitting.
