CRemove ballast to the after peak tank.
DAdd ballast to an amidships tank.
AI Explanation

The correct answer is B) Add ballast to the forepeak and after peak tanks. This is the correct answer because adding ballast to the forepeak and after peak tanks helps to reduce the bending moment and excessive sagging stress on the vessel. By adding ballast to these end tanks, the vessel's weight distribution is shifted towards the ends, which counteracts the sagging effect and reduces the overall bending moment. The other options are incorrect because: A) Removing ballast from an amidships tank would further exacerbate the sagging issue; C) Removing ballast from the after peak tank would not address the sagging problem; and D) Adding ballast to an amidships tank would not effectively counteract the sagging stress.
