The Correct Option is D
Solution and Explanation
Milk/primary teeth of man include 8 incisors, 4 canines and 8 molars (premolars are absent). Molars of milk teeth are shed off and premolars of permanent teeth take their place. The permanent teeth are 8 incisors, 4 canines, 8 premolars and 12 molars. Thus 12 teeth (8 premolars and 4 molars) are monophyodont (teeth which grow only once in life). Dental formulae of milk teeth and permanent teeth of human are given below.

Parts of the digestive system - Villi
Human Digestive System is the collection of organs that are responsible for digestion. It is a vital process that is driving the human race. The digestive system includes a digestive tract, which connects organs from the mouth to the large intestine.
Small Intestine
The Small intestine is an organ situated in the gastrointestinal tract where the food nutrients are absorbed completely. There is complete digestion of fats, proteins, and carbohydrates in the small intestine. It is the longest part of the alimentary canal ranging from 6 to 7.5 m. The small intestine of the human body is made up of three sections:
- Duodenum: It occurs in between the small intestine and jejunum.
- Jejunum: It is the second part of the small intestine. It is located in between the duodenum and ileum. There is the cell lining in the jejunum which is responsible for the absorption of nutrients. In this process, the surface area of the small intestine gradually increases because of the "villi". The villi are finger-like projections. Its function is to absorb some of the dietary nutrients such as amino acids, fatty acids, and sugars.
- Ileum: It is the third or the last part of the small intestine in the digestive system. It further opens into the large intestine.
