C. pleurodont
D. thecodont

Answer

### Step-by-Step Solution:

1. **Understanding the Types of Teeth**:
- The question asks about the type of teeth found in frogs. There are different types of teeth categorized based on their structure and attachment to the jaw.

2. **Analyzing the Options**:
- The options provided are:
- Acrodon
- Heterodon
- Plerodon
- Thecodon

3. **Defining Acrodon Teeth**:
- Acrodon teeth are characterized by being attached to the edge or surface of the jaw bone by a fibrous membrane, meaning they do not have roots. This type of attachment is typical in amphibians, including frogs.

4. **Reviewing Other Options**:
- **Heterodon**: These teeth vary in shape and serve different functions (like incisors, canines, and molars), which is not applicable to frogs.
- **Plerodon**: These teeth have longer roots and weak attachment, which is also not relevant to frogs.
- **Thecodon**: This type involves teeth that are completely enclosed in a deep socket of bone, found in mammals and crocodiles, not frogs.

5. **Conclusion**:
- Based on the definitions and characteristics of the teeth types, the correct answer is **Acrodon**. Frogs possess acrodon type teeth, which are attached to the jaw without roots.

### Final Answer:
The type of teeth in frogs is **Acrodon**.
