Options

A. Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 premolars. Molars are absent in milk teeth
B. Each half of the upper jaw and the lower jaw has 2 canines, 1 premolar, and 2 molars. incisors are absent in milk teeth
C. Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth
D. Each half of the upper jaw and the lower jaw has 2 incisors, 1 premolar, and 2 molars. Canines are absent in milk teeth

Answer

To solve the question regarding the dental formula for milk teeth in humans, we need to analyze the given formula `(2102)/(2102)` and understand what it represents.

### Step-by-Step Solution:

1. **Understanding the Dental Formula**: The dental formula `(2102)/(2102)` indicates the number of each type of tooth present in one half of the upper jaw and one half of the lower jaw. The numbers represent:
- 2 Incisors
- 1 Canine
- 0 Premolars
- 2 Molars

2. **Analyzing Each Half**: Since the formula is given for one half of the jaw, we need to consider that there are two halves (upper and lower) in the mouth. Thus, the total number of teeth can be calculated by multiplying the numbers in the formula by 2.

3. **Identifying the Types of Teeth**: In the case of milk teeth (deciduous teeth), the formula indicates:
- Each half has 2 incisors, 1 canine, and 2 molars, while premolars are absent.

4. **Conclusion**: Therefore, the dental formula `(2102)/(2102)` represents:
- Each half of the upper jaw and lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are not present in milk teeth.

5. **Selecting the Correct Option**: Based on this analysis, the correct option from the choices provided would be the one that states that each half of the upper jaw and lower jaw has 2 incisors, 1 canine, and 2 molars, with premolars absent.

### Final Answer:
The above formula represents that each half of the upper jaw and lower jaw has 2 incisors, 1 canine, and 2 molars, while premolars are absent in milk teeth.
