Verified
When both LS1 and LS2 are not actuated:
A) PLC program rung 1 is False.
B) PLC program rung 2 is True.
C) pilot light PL2 (O:2/6) is ON.
D) all of these.
PLC Program Rung
A horizontal row in a ladder logic diagram, which represents a logical operation performed in a PLC program.
Pilot Light PL2
An indicator light, often referred to by its identifier "PL2," used in control panels or machinery to signal operational status.

Final Answer :
D
Explanation :
When both LS1 and LS2 are not actuated, input X0 is False, which makes the conditions of both PLC program rung 1 and rung 2 False. Therefore, PLC program rung 1 is False and PLC program rung 2 is also False. As a result, output Y0 remains False, and pilot light PL2 (O:2/6) stays off. Therefore, all of the given choices are correct.
