Four words have been given out of which three are alike in some manner, while one is different. Choose the odd one.

* Bag, Basket, and Bowl are all stationary containers designed primarily for holding, storing, or carrying items by hand.
A Wheelbarrow is a small hand-driven vehicle with one or more wheels, specifically designed to transport heavy loads over distances.

Thus, Wheelbarrow is the odd one out because it is primarily classified as a moving vehicle/transportation tool rather than a simple handheld container.
