In pteridophytes, sporophytic plant body `:`

Options

A. Is differentiated into root, stem and leaf with gametangia
B. Is differentiated into rot, stem and leaf and bears sporangia
C. Is diploid with most advanced vascular tissues
D. More than one option is correct.

Answer

To answer the question regarding the sporophytic plant body in pteridophytes, we can break it down into several steps:

### Step-by-Step Solution:

1. **Understanding Pteridophytes**:
- Pteridophytes are a group of vascular plants that reproduce via spores. They include ferns, horsetails, and clubmosses.

2. **Sporophyte and Gametophyte**:
- The life cycle of pteridophytes is characterized by an alternation of generations. This means they have two distinct phases: the sporophyte (diploid) phase and the gametophyte (haploid) phase.
- The sporophyte is the dominant phase and is multicellular and diploid.

3. **Structure of the Sporophyte**:
- The sporophyte is differentiated into three main parts: roots, stems, and leaves.
- The leaves can be classified into microphylls (small leaves) and megaphylls (larger, more complex leaves).

4. **Presence of Gametangia**:
- The sporophyte can bear gametangia, which are structures that produce gametes. However, it is primarily the gametophyte that produces gametes.

5. **Sporangia**:
- The sporophyte also bears sporangia, which are structures that produce and contain spores.

6. **Vascular Tissue**:
- Pteridophytes have advanced vascular tissues compared to non-vascular plants. Their vascular system includes xylem and phloem, which are essential for the transport of water, nutrients, and food.

7. **Conclusion**:
- Based on the above points, we can conclude that the sporophytic plant body in pteridophytes is differentiated into root, stem, and leaves, bears sporangia, and has advanced vascular tissues. Therefore, more than one option is correct.

### Final Answer:
The correct answer is: **More than one option is correct.**
