D)either b or c.

Quizplus · Accepted Answer

A voltmeter reading of 24 VDC would indicate that the PB switch is closed and the input module is receiving power. However, it could also indicate a possible shorted PB or fault in the field wiring, as the voltmeter reading would be the same in all three scenarios. Therefore, the correct answer is D.
