In pteridophytes, the main plant body is a sporophyte which is differentiated into:

Options

A. Foot, seta and capsule
B. True root, stem and leaves
C. Vascular and non vascular tissues
D. Root-like, leaf-like or stem-like structures

Answer

**Step-by-Step Solution:**

1. **Understanding Pteridophytes**: Pteridophytes are a group of vascular plants that reproduce via spores and have a dominant sporophyte generation. This means that the main plant body is a sporophyte.

2. **Identifying the Main Plant Body**: In pteridophytes, the sporophyte is the main plant body, which is differentiated into various structures.

3. **Differentiation of the Sporophyte**: The sporophyte in pteridophytes is differentiated into three main parts:
- **True Roots**: These are the structures that anchor the plant and absorb water and nutrients from the soil.
- **Stems**: The stem supports the plant and is usually herbaceous (soft and green), facilitating the transport of nutrients and water.
- **Leaves**: The leaves are the sites for photosynthesis, allowing the plant to convert sunlight into energy.

4. **Conclusion**: Therefore, the correct answer to the question is that in pteridophytes, the main plant body (sporophyte) is differentiated into true roots, stems, and leaves.

**Final Answer**: True roots, stem, and leaves.
