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 this valve arrangement would allow the distillation plant to function properly. Valves "J", "K", "L", and "M" need to be open to allow the distillation process to occur, while valves "D" and "H" need to be closed to prevent any interruptions or leaks in the system. The other answer choices are incorrect because they either have the wrong combination of open and closed valves, or they are missing critical valves that need to be open or closed for the distillation plant to operate correctly.
