Topic: Voice,

Best Answer Explained in Below-:

The sentence “He helped me do it” indicates that someone provided assistance to the speaker in completing a task. When we convert this sentence into passive voice, we focus on the action being performed on the subject rather than who performed it.

Option B: “I was helped by him to do it” correctly rephrases the original sentence into passive voice. Here, "I" is the subject receiving help, "was helped" is the passive construction indicating that assistance was given, and "by him" specifies the agent who provided the help. The phrase "to do it" maintains the original meaning, clarifying what the help was directed towards.

In contrast, Option A suggests that the action was performed by him for the benefit of the speaker, which distorts the intended meaning. Option C is grammatically incorrect, and Option D lacks the necessary preposition ‘to,’ making it incomplete and thus incorrect. Overall, option B accurately captures the original sentence’s intent within a passive structure.
