Change narration: “Did Ayesha write a letter to her sister?”

The correct answer is Was a letter written by Ayesha to her sister? This question requires changing an active voice interrogative sentence in the Past Simple tense into its passive voice equivalent. The structure for a passive interrogative in Past Simple is: Was/Were + object + past participle + by + subject?

• B: Did a letter wrote by Ayesha to her sister? is incorrect because it uses "did" with "wrote" (incorrect past tense form for passive) and maintains an active-like structure.
• C: Was a letter being written by Ayesha to her sister? would be the passive form for a Past Continuous active sentence (e.g., "Was Ayesha writing a letter?").
• D: None of these is incorrect as option A is the correct transformation.
