Choose the correct option that gives the correct passive voice of the given sentence :
Have they done the work?

Question

Accepted Answer

The correct option is 2:

When converting an interrogative sentence from the Active Voice (Present Perfect Tense) to the Passive Voice, you must maintain the original tense while ensuring that the auxiliary verb agrees with the new subject (which was the object in the active sentence). The active sentence, "Have they done the work?", is in the Present Perfect Tense, using the structure *Have/Has + Subject + Past Participle*. In the passive transformation, the object, "the work," becomes the new subject. Since "the work" is singular, the auxiliary verb must change from "Have" to "Has." The passive structure for the Present Perfect Interrogative is *Has/Have + New Subject + been + Past Participle*. Therefore, the correct passive construction is "Has the work been done?"

The incorrect option is 1:

Option 1, "Have the work been done?", is grammatically incorrect due to subject-verb agreement. Since "the work" is a singular noun, it requires the singular auxiliary verb "Has," not the plural "Have."

The incorrect option is 3:

Option 3, "Had the work been done?", is incorrect because it changes the tense of the sentence from the Present Perfect to the Past Perfect. Passive voice must preserve the original tense, which in this case is the Present Perfect.

The incorrect option is 4:

Option 4, "Will the work be done?", is incorrect because it changes the tense of the sentence to the Future Simple Tense. This fundamentally alters the meaning and time frame of the original question, which is unacceptable in a passive voice transformation.
