Correct Answer:
C. Decisive
Ambivalent means having mixed, conflicting, or uncertain feelings about someone or something. Its opposite is decisive, which means being able to make clear and firm decisions without hesitation.
Why the other options are incorrect:
- Ambiguous: Means unclear or open to more than one interpretation. It is not an antonym of ambivalent.
- Wasteful: Means using resources carelessly or excessively and is unrelated to ambivalent.
- None of these: The correct antonym is Decisive.
