C. Nelumbo
D. Oxalis

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about very old and viable seeds, which indicates we need to identify a plant species known for its ancient seeds that can still germinate.

2. **Analyzing the Options**: We have four options to consider:
- **Phoenix Dactylae Fara (Date Palm)**: Known for its edible fruit but not specifically noted for ancient viable seeds.
- **Lupinus Arcticus (Lupine Plant)**: This plant is known for its seeds that have been recorded to germinate after thousands of years of dormancy.
- **Nilambo (Indian Lotus)**: While it is a long-living plant, it is not specifically recognized for ancient viable seeds.
- **Oxalis**: A wild edible plant, but again, not noted for its ancient seeds.

3. **Identifying the Correct Answer**: Among the options, **Lupinus Arcticus** stands out because it has been documented that its seeds can germinate after an estimated dormancy period of over 10,000 years. This makes it the most suitable answer to the question.

4. **Conclusion**: Therefore, the correct answer to the question "Very old and viable seeds are recorded in" is **Lupinus Arcticus**.
