Select the correct Active/Passive form of the given sentence.

Don’t touch the power switch with the wet hands.

You are forbidden to touch the power switch with the wet hands.

The correct Active/Passive form of the given sentence is You are forbidden to touch the power switch with the wet hands.

The original sentence is in the Active voice, with the subject "you" performing the action of "touching" the power switch. The passive voice of the sentence would have the power switch as the subject, and the action of "touching" would be performed on it. The correct passive voice form of the sentence would be "The power switch is forbidden to be touched with wet hands." However, this sentence is a bit awkward, so the more natural-sounding active voice form is preferred.

The other options are incorrect. Let the wet hands not be touched by the power switch is in the passive voice, but the subject of the sentence is "wet hands," which is not grammatically correct. Let the power switch not touched with the wet hands and Let the power switch not be touch by the wet hands are both grammatically incorrect, as they do not use the correct verb tense for the passive voice.
