Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A, C, and D only
Passive voice of a "Who" question:
- Object becomes subject: "Who taught you English?" has two objects, you and English; either can become the subject of the passive.
- Tense kept: the verb "taught" is simple past, so the passive is was/were + taught.
- Agent (by ...): the doer "who" becomes the agent:
- placed straight after "by", it takes the object form whom: "By whom ...?";
- when "by" moves to the end of the question, everyday English keeps who: "Who ... by?"
A. By whom were you taught English? — Correct. "You" is the subject, the verb is "were taught", and the agent is "by whom".
B. English was taught to you by who? — Incorrect. Straight after the preposition "by", the pronoun must be "whom"; the sentence also keeps statement word order instead of the form of a question.
Correct form: By whom was English taught to you?
C. Who were you taught English by? — Correct. This is the everyday form, with "by" at the end of the question.
D. By whom was English taught to you? — Correct. Here "English" is the subject, with "was taught" and the agent "by whom".
