The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Pteridophytes**: Pteridophytes are vascular plants that reproduce via spores rather than seeds. They are classified under the group called cryptogams, which means "hidden reproduction." 2. **Identifying Sporophylls**: Sporophylls are specialized leaves that bear spores. In pteridophytes, these sporophylls can aggregate to form distinct structures. 3. **Recognizing the Structure**: The distinct compact structure formed by sporophylls in pteridophytes is known as a "strobilus" (plural: strobili). This structure is often referred to as a cone. 4. **Function of Strobili**: The strobili serve to protect the spores and help in their dispersal. They can shield the spores from environmental conditions and herbivores. 5. **Examples**: A common example of a pteridophyte that has strobili is Equisetum, also known as horsetail. In Equisetum, the strobili are located at the terminal end of the stem. 6. **Conclusion**: Based on the information, the correct answer to the question is that in pteridophytes, sporophylls may form distinct compact structures called "strobili" or "cones." **Final Answer**: Strobili (or cones). ---
