"Why was such a letter written by your brother ?"

Why did your brother write such a letter?

The correct answer is Option (3) - Why did your brother write such a letter?

• Identifying the Passive Voice Structure:

  • The sentence is in the passive voice: "Why was such a letter written by your brother?"
  • It uses the structure: was + past participle ("written").

• Converting to Active Voice:

  • In active voice, the subject ("your brother") performs the action.
  • The verb changes from "was written" (passive) to "did write" (active) in the interrogative form.

• Option Analysis:

  • Option 1: Incorrect because it retains the passive structure with "has been written."
  • Option 2: Incorrect because "did your brother wrote" is grammatically wrong (past tense "wrote" cannot follow "did").
  • Option 3: Correct because it correctly forms the active voice: "Why did your brother write such a letter?"
  • Option 4: Incorrect because it retains the passive structure with "was being written."
