Step 1: Understanding Passive Voice:
In passive voice, the subject of the sentence receives the action. The tense in the passive voice should match the tense in the active voice. Since the sentence is in past perfect ("had written"), the passive voice should also be in past perfect ("had been written"). Step 2: Analyzing the Options:
- A letter had been written by Veena: This is the correct passive construction in past perfect tense.
- A letter is wrote by Veena: This is grammatically incorrect because the verb "wrote" should be in the past participle form, "written."
- A letter was written by Veena: This is in past simple tense, which is not suitable here because the original sentence is in past perfect tense.
- Write a letter by Veena: This is incorrect because it uses the base form of the verb "write" and does not follow the passive voice structure. Step 3: Conclusion:
The correct passive sentence is A letter had been written by Veena.
