Select the option that expresses the given sentence in passive voice.

Have you written the right answer?

Has the right answer been written by you?

The correct passive voice of the given sentence is Has the right answer been written by you?

The active voice of the sentence is Have you written the right answer? This sentence is in the present perfect tense, which is used to describe an action that has happened in the past, but the time of the action is not specified. The passive voice of the sentence is formed by putting the subject of the active sentence after the verb "to be" and the past participle of the main verb. In this case, the subject of the active sentence is "you" and the main verb is "write." The past participle of "write" is "written." So, the passive form of the sentence is Has the right answer been written by you?

The other options are incorrect because:

• Was the right answer been written by you? is in the past perfect tense, while the original sentence is in the present perfect tense.
• Have the right answer been written by you? is grammatically incorrect. The subject of the passive sentence is singular, so the verb "have" should be "has."
• Has the right answer being written by you? is grammatically incorrect. The verb "being" is not used with the past participle of the verb "write."
