The term "load on top" is the name of a method used on many crude oil carriers for the purpose of __________.

Correct Answer: Option C — the loading of new cargo into a decanted slop tank as a procedure to minimize pollution

Load on top is a MARPOL-compliant procedure used to minimize oil pollution. After decanting water from the slop tank, new cargo is loaded directly on top of the remaining oil residue. This process consolidates oily waste, allowing for the discharge of clean water while retaining oil for shore-side disposal.
