Which one of the following is not the example of 'Pack Animals'?

Elephants

The correct answer is Option (4) → Elephants

Elephants are not considered pack animals in the same way as dogs, mules, and camels.

Pack animals are generally animals that are domesticated and trained to carry goods or equipment on their backs as part of their work.  Horses are used as a draught animal even in the Western countries. Dogs and reindeer are used in North America, North Europe and Siberia to draw sledges over snow-covered ground. Mules are preferred in the mountainous regions; while camels are used for caravan movement in deserts. In India, bullocks are used for pulling carts.
