70% to passWhich of the valve arrangements listed would be correct for operating the distillation plant shown in the illustration? Illustration MO-0111
AValves "C", "J", "K", "L", "M" open, valves "A", "B", "D", and "H" closed.
BValves "D", "H", "J", "K", "L", "M" open, valves "I", "G", "F", and "E" closed.
CValves "H", "J", "K", "L", "M" open, valve "D" closed.
DValves "J", "K", "L", "M" open, valves "D" and "H" closed.
AI Explanation
The correct answer is D) Valves "J", "K", "L", "M" open, valves "D" and "H" closed. This is the correct answer because the illustration MO-0111 shows the distillation plant in operation, and the correct valve arrangement for this operation is to have valves "J", "K", "L", and "M" open to allow the flow of distilled water, while valves "D" and "H" should be closed to prevent the ingress of untreated water or the escape of distilled water. The other options are incorrect because they either have the wrong combination of open and closed valves, or they include valves that should be in the opposite state for the distillation plant to function properly.
