Select the correct passive form of the given sentence.
"The editor has approved the final version."
Show answer & explanation
Correct answer: A
Explanation
Active to passive voice transformation:
Active Voice Structure: Subject (The editor) + has/have + Past Participle (approved) + Object (the final version). This is the Present Perfect tense.
Passive Voice Rule: To convert Present Perfect active to passive, use the formula: Object + has/have + been + Past Participle + (by + Subject).
Application:
The object "the final version" becomes the new subject.
Since "the final version" is singular, we use "has been".
The past participle remains "approved".
The original subject is added with "by the editor".
Passive voice: The final version has been approved by the editor.
