What is the proper action for a Class E driver when a draft horse shows signs of extreme fatigue or heat stress (golpe de calor / deshidratación) in hot summer weather?

1. Whip the animal to make it run faster
2. Immediately pull off the road into a shaded area, loosen the harness and remove the collar, offer fresh drinking water (not ice cold), sponge down the neck and legs with cool water, and allow the animal to rest until fully recovered
3. Leave the horse in the hot sun with the loaded cart
4. Pour boiling water on the horse
