Question 298Motor Plants - Assistant Engineer

The correct answer is C) Q. The closing sequence at the end of the desludging cycle is initiated by opening the component labeled Q. This is because Q is the valve that controls the opening and closing of the desludging cycle. By opening Q, the system is able to complete the desludging process and return to its normal operating state. The other options are incorrect because F, P, and R are not the components responsible for initiating the closing sequence of the desludging cycle. They likely serve other functions within the overall system, but do not directly control the completion of the desludging process.
