After fuel tanks have been filled and bunkers completed, which of the listed procedures should be followed next?

Correct Answer: Option A — The tanks should be sounded to verify levels.

Sounding tanks after bunkering is a critical safety and environmental requirement to verify actual volumes against calculated intake. This confirms that no tank has been overfilled, which could lead to an accidental discharge, and ensures the vessel's stability and trim remain within the parameters defined by the stability letter.
