Our teeth are

Options

A. Acrodont and homodont
B. Homodont and polyphyodont
C. Thecodont, diphyodont and heterodont
D. Acrodont, homodont and polyphyodont

Answer

### Step-by-Step Solution:

1. **Identify the Types of Teeth**:
- In humans, there are four types of teeth:
- Incisors
- Canines
- Premolars
- Molars

2. **Determine the Classification of Teeth**:
- Humans have different types of teeth, which means they are classified as **heterodont** (having different types of teeth) rather than **homodont** (having the same type of teeth).

3. **Understand the Number of Sets of Teeth**:
- Humans typically have two sets of teeth throughout their lifetime:
- Primary teeth (also known as milk teeth)
- Permanent teeth

This classification is referred to as **diphydont**.

4. **Examine the Arrangement of Teeth**:
- Teeth are embedded in sockets within the jawbone, which is referred to as **thecodont** arrangement.

5. **Conclusion**:
- Therefore, the correct classification of human teeth is:
- Heterodont (different types)
- Diphydont (two sets)
- Thecodont (teeth embedded in sockets)

### Final Answer:
Humans have heterodont teeth that are diphyodont and thecodont.
