Concept:The question tests the ability to identify an antonym that fits the sentence context correctly.Explanation:The underlined word is “convicted”, which means declared guilty of a criminal offence by a court.To fill the gap, we need a word that is opposite in meaning and grammatically fits.“Acquitted” means freed from a criminal charge by a verdict of not guilty.This is the direct opposite of “convicted”.The other options do not convey the legal opposite meaning.Answer:D. acquitted
