D. Angiosperms

Answer

To solve the question "Plants having vascular tissues but lacking seeds are," we need to analyze the options provided and determine which one fits the criteria of having vascular tissues (xylem and phloem) but not producing seeds.

### Step-by-Step Solution:

1. **Understand the Question**:
- We are looking for plants that have vascular tissues (which include xylem and phloem) but do not produce seeds.

2. **Analyze the Options**:
- **Option 1: Bryophytes**
- Bryophytes are non-vascular plants. They do not have xylem and phloem, and they reproduce via spores. Therefore, they do not fit the criteria.
- **Option 2: Pteridophytes**
- Pteridophytes are vascular plants that include ferns and horsetails. They have xylem and phloem and reproduce via spores, not seeds. This option fits the criteria.
- **Option 3: Gymnosperms**
- Gymnosperms are vascular plants that produce naked seeds. They do not fit the criteria as they do have seeds.
- **Option 4: Angiosperms**
- Angiosperms are vascular plants that produce seeds enclosed in fruits. They also do not fit the criteria as they have seeds.

3. **Conclusion**:
- The only group of plants that has vascular tissues and does not produce seeds is **Pteridophytes**. Therefore, the correct answer is **Option 2: Pteridophytes**.

### Final Answer:
Plants having vascular tissues but lacking seeds are **Pteridophytes**.
