Answer: B) To work with electrical wires, you need to use extreme caution.
Explanation: A dangling modifier is a type of misplaced modifier that makes the meaning of the sentence unclear because it isn't clear what the modifier is referring to. In the given sentence it isn't clear who is the subject of the sentence or what is the modifier's function, so the revision that most effectively corrects the dangling modifier in the sentence is "To work with electrical wires, you need to use extreme caution."
