What does a stable do when it offers horses for hire?

A stable that offers horses for hire essentially provides a service where individuals can rent horses for various activities, such as riding, lessons, or therapeutic sessions. This rental service allows for broader accessibility to horseback riding experiences without requiring individuals to own a horse. The stable would typically manage the horses' care and maintenance while facilitating a safe environment for both the horses and riders.

Other options, while they may relate to the horse industry, do not accurately represent the core function of a stable that hires out horses. Providing housing for equine only pertains to boarding facilities and does not encompass offering rentals. Organizing equine competitions focuses on events rather than the immediate rental service. Selling equines to customers indicates a different business model that does not involve renting horses for temporary use. Hence, the primary role of such a stable is to rent horses for various activities, making this choice the most fitting answer.
