Find the odd number / letters / word from the given alternative:

The answer is D. Cow : Shed.

A garage is a building or structure where vehicles are kept, a sty is a pen or enclosure for pigs, and a stable is a building or enclosure for horses. A shed is a small building or shelter, typically used for storage or as a workshop.

While a shed can be used to house a cow, it is not the most common or traditional type of housing for cows. Cows are typically housed in barns, which are larger and more well-suited to their needs. Sheds are more commonly used for housing smaller animals, such as chickens or rabbits.

Therefore, the odd word in the list is “shed”.
