Explanation

**Step-by-Step Solution:**

1. **Identify the Classification of Pteridophytes:**
Pteridophytes are a group of vascular plants that reproduce via spores instead of seeds. They are part of the plant kingdom and are known for their unique reproductive methods.

2. **Understand the Term "Cryptogams":**
The term "Cryptogams" refers to plants that do not produce flowers or seeds. Instead, their reproductive structures are hidden, as they reproduce through spores. This classification includes ferns, mosses, and algae.

3. **Relate Pteridophytes to Cryptogams:**
Since Pteridophytes reproduce through spores and do not form flowers or seeds, they fall under the category of Cryptogams. Therefore, Pteridophytes are also called Cryptogams.

4. **Clarify Other Terms:**
The term "Phenogams" is used for plants that produce seeds and have vascular bundles. This term is not applicable to Pteridophytes, as they do not fit this description.

5. **Conclusion:**
Based on the classification and reproductive characteristics, the correct answer is that Pteridophytes are also called Cryptogams.
