Step 1: Note that the question asks for the OPPOSITE (antonym), not a synonym. Step 2: Analyse the target word — 'courageous' means brave and willing to face danger or difficulty without fear. Step 3: Find the antonym — the opposite of courageous is 'timid', meaning lacking bravery and easily frightened. 'Bold' is a synonym, 'reckless' is related but not an antonym, and 'strong' is about physical ability, not courage.
