Which of the following statements represents the two major functions provided by the item labeled "20" shown in the illustration? Illustration MO-0111

Correct Answer: Option D — The pump supplies the motive fluid to the ejectors in addition to supplying the feedwater to the distiller.

Item '20' is the ejector pump, which serves two critical roles in the distiller operation. It provides the high-pressure motive fluid required to operate the air ejectors for vacuum maintenance, and it simultaneously supplies the necessary sea water feedwater to the evaporator shell for the distillation process to occur.
