Why this is the answer
This question rewards a core test strategy: using word parts to estimate meaning. The prefix BENE- means good or well (as in 'benefit' and 'beneficial'), so BENEVOLENT — which also contains a root related to 'wishing' (vol-) — most reasonably means kind, generous, and well-meaning. Even without having memorized the word, recognizing BENE- = good steers you toward the positive choice and away from 'harmful.' When you face an unknown word, break it into prefix, root, and suffix; the pieces often reveal whether the meaning is positive or negative and point to the best answer.
