Which equipment is included in the tack used during horse training?

The selection of saddles and bridles as the correct answer reflects the essential items included in the tack for horse training. Tack refers to the equipment and accessories used in the management of horses, particularly during riding and training sessions. Saddles provide a seat for the rider and distribute their weight evenly across the horse's back, which is critical for the animal's comfort and movement. Bridles, on the other hand, play a crucial role in communication between the rider and the horse, allowing the rider to guide and control the horse through pressure on the mouth and head.

While other items like saddle pads and bits are important components of tack, they do not encompass the full breadth of what constitutes the essential equipment for effective horse training. Saddle pads, for example, are used for protection and comfort, but they are not as fundamental as the saddle and bridle, which are used directly in managing the horse during training and riding. The choice of saddles and bridles captures the core components of the tack used in training, making it the most comprehensive and accurate response.
