Final answer:
Optoin B. Molars and premolars are the types of teeth predominantly used for crushing and grinding food. Molars have several pointed cusps, while premolars, also called bicuspids, have two cusps for mashing food.
Step-by-step explanation:
Among the multiple types of teeth, molars and premolars are used predominantly for crushing and grinding. Premolars, also known as bicuspids, have two rounded cusps that are useful for mashing foods, while molars are the largest teeth with several pointed cusps that crush food to prepare it for swallowing. This includes the wisdom teeth, which are the third molars and are often removed if they fail to erupt properly. Incisors are the sharp front teeth used for biting into food, such as when you bite into an apple, and canines are fang-like teeth used for piercing tougher foods.
With their different types of teeth, mammals can consume a wide range of different kinds of foods. The human dentition, with its variety of incisors, canines, bicuspids, and molars, reflects this adaptability. Most mammals are diphyodonts, which means they have two sets of teeth during their lifetime: deciduous ("baby") teeth and permanent teeth, allowing them to efficiently process foods throughout different stages of life.
