Select the appropriate antonym for the underlined word.

They must have been more than just suspicious of you.

Definitive 

The correct answer is option 2. Definitive.

"Suspicious" typically means having or showing a cautious distrust of someone or something.

The antonym we're looking for should describe the opposite sentiment—having confidence or trust in someone or something.

"Definitive" fits this description perfectly. It means conclusive or final, implying certainty or confidence in a decision or judgment.

Therefore, "definitive" is the appropriate antonym for "suspicious" because it represents the opposite characteristic—having confidence or trust instead of distrust or caution.
