Select the option that expresses the given sentence in passive voice. Don’t let Dylan fool you!

Correct — C. The stem is a negative imperative built on let + object + bare infinitive: Do not let Dylan fool you.

Rule: the passive of such an imperative is Do not be + past participle, with the old subject moved into a by phrase.

The object of the inner verb is you, and that is what the passive promotes. An imperative already addresses the listener, so the promoted subject is simply left unsaid.

Fool must then become the past participle fooled after be, giving Do not be fooled by Dylan → option (c).

Why the others are wrong

• (a)
  Do not ever be fooled by Dylan. — This is grammatical, but it inserts ever, an emphasis word with nothing to translate it in the active sentence. A voice change rewrites structure and may not add meaning.
• (b)
  Do not be fool by Dylan. — This keeps the base form fool after be. A passive needs be plus the past participle, so it has to be fooled — be fool is not a possible verb phrase.
• (d)
  Do not have been fooled by Dylan. — Have been fooled is a perfect form, and it points at completed past time. An imperative instructs the listener about what to do next, so it cannot take a perfect.

Voice change on an imperative follows its own template, because an imperative has no stated subject to swap with the object.

The active pattern here is let + object + bare infinitive. The object of the inner verb, you, is what the passive promotes, and because the command already addresses that listener, the subject goes unwritten.

What is left is the command be + past participle, negated as Do not be fooled. The old subject Dylan moves into the by phrase.

Nothing else may change. A voice change is a structural rewrite, never a rephrasing.

Key facts

• The passive of an imperative drops the subject, because the imperative already addresses the listener.
• A passive verb phrase is be plus the past participle, so fool becomes fooled.
• In Let + object + be + past participle, the object of the active verb becomes the passive subject.
• A voice change rewrites structure only, so an option that adds a word such as ever no longer matches the active sentence.

Common traps

• Picking the version with ever because it sounds more emphatic, when the active sentence has no such word.
• Writing be fool instead of be fooled, which is the commonest participle slip in passive items.
• Keeping you as a written subject and producing You should not be fooled, which turns a command into advice.
