Correct Answer:
C. Compassionate
The correct answer is Compassionate. The word "ruthless" means showing no pity or compassion; cruel. The opposite (antonym) of ruthless is someone who shows kindness and sympathy. Among the options:
- Cruel: This is a synonym (same meaning) of ruthless, not an antonym.
- Harsh: Also a synonym, meaning severe or unkind.
- Compassionate: Means showing concern for others' suffering; this is the direct opposite of ruthless.
- Merciless: Another synonym of ruthless.
Therefore, the correct antonym is "Compassionate".
