✅ Correct Answer: (b) Orangutan
🧑🏫 Classroom Explanation
Among the given animals, orangutans are well-documented users of tools in the wild.

- They also use leaves as gloves, umbrellas, and sponges, showing advanced problem-solving ability.
- This behaviour reflects cognitive sophistication and learning capacity among great apes.
Other options:
- Fishing cat – uses claws and paws, not tools
