In the horse, what is the make-up of molars?

The correct answer reflects the typical dental formula for equines, which encompasses the arrangement of premolars and molars in a horse's mouth. In an adult horse, the dental formula typically includes three premolars on each side of the jaw and three molars, resulting in a total of six premolars and six molars for a complete set when accounting for both sides of the mouth.

Machining this match, it’s important to note that premolars and molars serve distinct functions in the horse’s diet; premolars are mainly involved in the grinding and processing of forage, whereas molars continue this process as the horse chews its food.

This distribution is why the choice indicating three premolars and three molars for a total of six is accurate in the context of what you’ll find in a horse's mouth. The other options either overestimate or underestimate the count, leading to confusion regarding the equine dental anatomy.
