By whom have these facts been verified?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Who has verified these facts?
- The correct active form is "Who has verified these facts?" because it correctly shifts the focus from the passive construction to an active one.
- In the passive form, "By whom have these facts been verified?" the verb "have been verified" is in the present perfect tense.
- To convert this to active voice, we use the present perfect form "has verified" with the subject "who" to indicate the person performing the action.
