Convert into Passive Voice;"The boy has rung the bell."

Explanation

In the sentence 'The boy has rung the bell', 'the boy' is the subject who performs the action, and 'the bell' is the object receiving the action. To convert this to passive voice, we make 'the bell' the subject of the sentence and use the appropriate form of the verb 'to be' combined with the past participle 'rung'. Thus, the correct transformation is 'The bell has been rung by the boy', which is option A.Option B ('The bell was being rung by the boy') implies that the action was ongoing, which is not correct as the original sentence indicates a completed action.Option C is incorrect due to the awkward and improper construction 'has been being', which is rarely used in English.Option D is also a passive construction but changes the tense to simple past, which does not align with the present perfect tense of the original sentence.
