Final answer:
A 12-foot stall is the most common and the smallest comfortable size for today's large horses. Option c is correct.
Step-by-step explanation:
A 12-foot stall is the most common and the smallest comfortable size for today's large horses. Horse stalls are designed to give horses enough space to move around, lie down, and turn comfortably. The stall size can have a significant impact on the welfare and health of a horse as they spend several hours a day in their stall.
A standard horse stall size for a large horse is usually 12 feet by 12 feet. This allows enough space for the horse to lay down and get up without difficulty, helps prevent stress, and reduces the risk of injury. Smaller stalls, such as 8 or 10 feet, might be too restrictive, especially for larger breeds or those with higher activity needs.
When considering stall sizes for horses, it's also important to take into account the horse's individual needs, including their size, breed, and the amount of time they will be spending in the stall. Builders and barn owners often opt for larger stall sizes if space and resources allow, to provide the best environment for the horses' wellbeing.
