D. Can't say

Answer

To answer the question regarding the type of fertilization in fungi, bryophytes, and pteridophytes, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Fertilization Types**:
- Fertilization can be classified into two main types: internal and external.
- Internal fertilization occurs when the fusion of male and female gametes takes place inside the female organism.
- External fertilization occurs when gametes fuse outside the female organism.

2. **Fertilization in Fungi**:
- In fungi, fertilization typically involves the fusion of gametes that occurs in a moist environment, but it can be considered as a form of internal fertilization since the gametes are often retained in structures that provide protection.

3. **Fertilization in Bryophytes**:
- In bryophytes (like mosses), fertilization occurs inside the archegonium, which is the female reproductive structure. The sperm swims to the egg within this structure, leading to internal fertilization.

4. **Fertilization in Pteridophytes**:
- In pteridophytes (like ferns), fertilization also occurs within the archegonium. The sperm swims through water to reach the egg, which is again a form of internal fertilization since it occurs within the female reproductive organ.

5. **Conclusion**:
- Based on the above points, we can conclude that in fungi, bryophytes, and pteridophytes, the fertilization is primarily internal.

### Final Answer:
In fungi, bryophytes, and pteridophytes, the fertilization is **internal**.
