Convert from active to passive voice:
Who will have broken the chair?

When a sentence is written in passive voice instead of active voice, the subject and object of the phrase switch places, putting the emphasis on the verb's action that the subject has received. With the help of an auxiliary verb and a past participle, the sentence's verb takes on a passive form.

The future perfect tense of the text is maintained while Option A correctly changes the active to passive.

Options B, C, and D are unsatisfactory since they do not use the future perfect tense.
