The correct answer is: c) Both a & b.

Donkeys and elephants are both traditional modes of transport used for carrying goods in hilly regions of Manipur. Donkeys are small, sturdy animals that are well-suited to carrying heavy loads over rough terrain. Elephants are larger and stronger than donkeys, and they can carry even heavier loads. Both animals are essential for transporting goods in the hilly regions of Manipur, where roads are often impassable.
