Complete the sentence with the correct form of SUSPECT: The police found his behaviour highly ______.

Answer and explanation

Correct answer: C. suspicious

  1. Step 1: An adjective describing behaviour is needed.
Answer
suspicious.
Why not the others: "suspicion" is wrong because a noun does not fit after 'highly'. "suspiciously" is wrong because an adverb cannot follow 'found his behaviour highly'. "suspected" is wrong because 'suspected' describes people believed to be guilty.
