Modern day (Advanced) plants are:-

Options

A. Monocots
B. Dicots
C. Gnetales
D. Ferns

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Classification**:
- Plants are classified into two main groups: Bryophytes (non-vascular) and Tracheophytes (vascular).

2. **Identifying Vascular Plants**:
- Tracheophytes include ferns, gymnosperms, and angiosperms. The key feature of these plants is the presence of vascular tissues (xylem and phloem).

3. **Evolution of Angiosperms**:
- Angiosperms (flowering plants) are believed to have evolved from a group of gymnosperms known as Cnetophytes.

4. **Understanding the Evolutionary Order**:
- Within angiosperms, there are two main categories: dicots and monocots. Dicots are considered to have evolved first, followed by monocots.

5. **Comparing Monocots and Dicots**:
- Since monocots evolved after dicots, they are considered more advanced in terms of evolutionary development.

6. **Eliminating Other Options**:
- Ferns and kneetails are less advanced compared to gymnosperms and angiosperms, making them not suitable answers for modern-day advanced plants.

7. **Conclusion**:
- Based on the evolutionary sequence, monocots are identified as the more advanced group of plants compared to dicots. Therefore, the correct answer is monocots.

**Final Answer**: Monocots are the modern-day advanced plants.
