Step 1: Break the word into its parts. 'Benevolent' combines the Latin prefix 'bene-' (good, well) with 'volens' (wishing), so it means wishing good things for others, i.e., kind-hearted.
Step 2: For the antonym, look for a word built the opposite way, replacing 'bene-' (good) with a prefix meaning bad or ill. 'Malevolent' uses 'male-' (bad, ill) with the same root 'volens', giving the meaning of wishing harm on others.
Step 3: Confirm the other three options do not fit: 'kind', 'generous', and 'charitable' all describe good will toward others, the same direction as 'benevolent', not the opposite.
Correct option: (4) Malevolent.
