The House of Horse is called Stable

A stable is a building or structure designed to house horses. It is their shelter, much like a kennel is for a dog. The term "stable" is commonly used to refer to a building where horses are kept, fed, and taken care of.

Explanation:
The house of a horse is called a stable. Here is an explanation of why the correct answer is option 'B':

1. Kennel:
A kennel is a house or shelter for dogs. It is not the correct term for a horse's house. Horses and dogs are different animals with different housing needs, so a horse would not be kept in a kennel.

2. Stable:
A stable is a building specifically designed for horses. It provides shelter, protection, and a safe environment for horses. Stables are usually large structures with multiple stalls or compartments where horses can be kept individually. They are equipped with feeding and watering areas, as well as spaces for grooming and tacking up the horses.

3. Shed:
A shed is a simple, often small, structure used for storage or as a workshop. While horses may occasionally seek shelter in a shed if available, it is not specifically designed for their needs. Horses require a more spacious and specialized structure like a stable.

4. Den:
A den is a term used for the homes of certain animals, such as wolves or foxes. It is not a term commonly associated with horses. Horses are not den animals and do not live in dens like other species do.

In conclusion, the correct term for the house of a horse is a stable. This is because stables are specifically designed to meet the housing and care needs of horses, providing them with a safe and comfortable environment.
