A. English is taught by whom
B. By whom has English been taught
C. By whom were you taught English
D. By whom are you taught English
🧠 Explanation:
Passive voice transforms the focus from the doer to the receiver. “By whom are you taught English” uses “taught” as a past participle and “are” as a helping verb. “Passive voice” is a noun phrase. Alternatives could vary in phrasing but must maintain grammatical accuracy in English.
