Show answer & explanation
Correct answer: A
Explanation
Correct Answer
Had invitation cards been sent by her to all the guests on Monday?
Explanation
The given sentence is in the past perfect interrogative active voice ("Had she sent..."). In passive voice, the structure changes to Had + object + been + past participle (V³) + by + subject. Therefore, the correct sentence is:
"Had invitation cards been sent by her to all the guests on Monday?"
The other options are incorrect. Option 2 changes the tense to present perfect. Option 3 changes the tense to simple past. Option 4 is grammatically incorrect because it uses "send" instead of the past participle "sent."
Key Points
For past perfect interrogative sentences, the passive voice structure is:
Had + object + been + V³ + by + subject?
Always preserve the original tense and meaning while changing the voice.
