Which of the conditions listed would indicate a large condenser tube leak within the distiller shown in the illustration? Illustration MO-0111

Correct Answer: Option A — The activation of the salinity monitoring equipment's annunciator circuit.

A condenser tube leak introduces untreated or contaminated cooling water directly into the potable water distillate circuit. This sudden impurity spike triggers the salinity cell, sounding the alarm to prevent contaminated water from entering the ship's potable water tanks.
