D. Pholidota .

Answer

**Step-by-Step Solution:**

1. **Understanding Gnawing Teeth**: Gnawing teeth are specialized teeth that are adapted for biting and chewing food. These teeth are particularly prominent in certain groups of mammals.

2. **Identifying the Groups**: The question provides four options:
- Rodentia
- Lagomorpha
- Both A and B
- Folivora

3. **Characteristics of Rodentia**: Rodents are characterized by their continuously growing incisors. These teeth are used for gnawing, which is essential for their feeding habits.

4. **Characteristics of Lagomorpha**: Lagomorphs, which include rabbits and hares, also possess incisors that are similar to those of rodents. They too have gnawing teeth that help them in their feeding.

5. **Analyzing Folivora**: Folivora, which includes sloths, do not possess gnawing teeth like rodents and lagomorphs. Instead, they have different adaptations for their diet.

6. **Conclusion**: Since both Rodentia and Lagomorpha have gnawing teeth, the correct answer to the question is "Both A and B."

**Final Answer**: Both A and B (Rodentia and Lagomorpha)
