Dental formula in human beings is

Options

A. `(3223)/(3223)`
B. `(2123)/(2123)`
C. `(1232)/(1232)`
D. `(2233)/(2233)`

Explanation

**Step-by-Step Solution:**

1. **Understanding Dental Formula**: The dental formula is a way to represent the number and types of teeth present in an organism. In humans, it is expressed in a specific format that shows the number of each type of tooth in the upper and lower jaws.

2. **Types of Teeth**: Humans have four types of teeth:
- Incisors: Used for cutting food.
- Canines: Used for tearing food.
- Premolars: Used for crushing and grinding food.
- Molars: Also used for grinding food.

3. **Counting Teeth in the Upper Jaw**:
- In the upper jaw, the number of each type of tooth is as follows:
- Incisors: 2
- Canines: 1
- Premolars: 2
- Molars: 3

4. **Counting Teeth in the Lower Jaw**:
- In the lower jaw, the number of each type of tooth is:
- Incisors: 2
- Canines: 1
- Premolars: 2
- Molars: 3

5. **Formulating the Dental Formula**:
- The dental formula is written by combining the counts from the upper and lower jaws. It is represented as:
- Upper Jaw: 2 (Incisors) - 1 (Canines) - 2 (Premolars) - 3 (Molars)
- Lower Jaw: 2 (Incisors) - 1 (Canines) - 2 (Premolars) - 3 (Molars)
- This gives us the complete dental formula for humans as:
- **2/1/2/3 | 2/1/2/3**

6. **Conclusion**: Therefore, the dental formula in human beings is **2/1/2/3 | 2/1/2/3**.
