AI Explanation
The correct answer is B) 3, 4, 5, 6, and 24. According to the illustration MO-0111, heat exchangers 3, 4, 5, 6, and 24 use sea water as a cooling medium. This is evident from the cooling water flow paths shown in the diagram, where sea water is directed through these specific heat exchangers. The other options are incorrect because: - Option A incorrectly includes heat exchanger 23, which is not cooled by sea water. - Options C and D incorrectly exclude heat exchanger 3 from the list of sea water-cooled heat exchangers.
