Spore bearing tracheophytes:-

Options

A. Pteridophyta
B. Gymnosperms
C. Angiosperms
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Spore-Bearing Tracheophytes:**
- Tracheophytes are vascular plants that have specialized tissues (xylem and phloem) for the transport of water, nutrients, and food.
- Spore-bearing plants reproduce through spores rather than seeds.

2. **Analyzing the Options:**
- **Option 1: Tridophyta**
- Tridophyta (or Pteridophytes) are indeed vascular plants that reproduce via spores. They include ferns and horsetails, which are known for their spore production.
- **Conclusion:** This option is correct.

- **Option 2: Gymnosperms**
- Gymnosperms, such as conifers, also produce spores. They have a life cycle that includes a stage where spores are produced, although they mainly reproduce through seeds.
- **Conclusion:** This option is also correct.

- **Option 3: Angiosperms**
- Angiosperms are flowering plants that primarily reproduce through seeds. However, they do have a life cycle stage that involves spores (specifically in their gametophyte stage).
- **Conclusion:** This option can be considered correct in a broader sense, as they do have a spore-producing phase.

3. **Final Option: All of the Above**
- Since all the previous options (Tridophyta, Gymnosperms, and Angiosperms) can be associated with spore production in some capacity, the option "All of the above" is correct.
- **Conclusion:** The correct answer is option 4, "All of the above."

**Final Answer:** All of the above (Option 4) are spore-bearing tracheophytes.
