Which of the following sentences is correctly formed?

The correct answer is Option (3) → The customs officer found nothing unusual in my uncle’s suitcase at the airport.

Adjective after “nothing”:

• Words like “something”, “anything”, “nothing” and “someone” take the adjective right after them.
• Here the adjective “unusual” comes straight after “nothing”: found nothing unusual.
• The other options put “unusual” before “nothing” or before the verb, or put “nothing unusual” before the verb “found”. The object must come after the verb.
