The molars (12 in number) are the largest teeth of all whereas the premolars (8 in number) present next to molars.
The function of these types of teeth is similar, i.e. crushing and grinding of food.

Explanation:
Different types of teeth:
There are four types of teeth present in humans, namely incisors, canines, premolars, and molars. Each type of tooth has a specific function and structure.
Structure and function of teeth:
The incisors are the front teeth that are used for biting and cutting food. They have a sharp, thin edge that helps in cutting food. The canines are the next teeth present on either side of the incisors. They are pointed and sharp and are used for tearing and ripping food. The premolars are located between the canines and molars and are used for chewing and grinding food. The molars are the back teeth and are used for grinding and crushing food.
Comparison of molars and premolars:
Molars and premolars are similar in function as they are both used for chewing and grinding food. However, they differ in structure. Molars have a larger surface area and are more complex in structure than premolars. Molars have four or five cusps, while premolars have two cusps.
Conclusion:
Hence, the correct answer to the question is option B, i.e., molars and premolars differ in structure but are similar in function.
