C
the remainder is stripped to one tank and then pumped out with the main pumps
D
the remainder is gravitated to the centers from the wings and pumped out with the main pumps
AI Explanation
The correct answer is C) the remainder is stripped to one tank and then pumped out with the main pumps. When discharging a cargo on a tankship, the main cargo pumps can only handle a certain amount of the remaining oil. The rest of the oil, known as the "stripping", needs to be moved to a single tank before it can be pumped out. This is done by using smaller stripping pumps to consolidate the remaining oil into one tank, which can then be pumped out using the main cargo pumps. The other options are incorrect because they do not accurately describe this standard stripping process.
