This is an example of a very old viable seed excavated from Arctic Tundra. The seed germinated and flowered after an estimated record to 10,000 years of dormancy. It is

Options

A. Victoria
B. Lupinus arcticus
C. Phoenix dactylifera
D. Strobilanthus kunthiana

Explanation

To solve the question regarding the very old viable seed excavated from the Arctic tundra that germinated and flowered after an estimated 10,000 years of dormancy, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question refers to a seed that has remained dormant for an extremely long period, specifically 10,000 years, and is capable of germination and flowering after this dormancy.

2. **Identify Key Terms**:
- **Viable Seed**: A seed that is capable of germination.
- **Dormancy**: A period during which a seed is alive but not actively growing.

3. **Analyze the Options**: The options provided are:
- Victoria
- Lupinus
- Arcticus
- Phoenix
- Tactilefera
- Strobilanthus
- Gunthenia

4. **Consider Known Facts**:
- The seed in question is known to be from the Arctic tundra.
- The scientific name of the plant is crucial for identifying the correct option.

5. **Recall Relevant Information**:
- The plant known to have seeds that can remain viable for thousands of years is **Lupinus arcticus** (commonly known as Arctic lupine).
- Other options like Victoria and Phoenix have seeds that can remain viable but do not match the 10,000-year dormancy.

6. **Eliminate Incorrect Options**:
- **Victoria**: Seeds viable for hundreds of years but not 10,000.
- **Phoenix dactylifera**: Date palm seeds have been known to germinate after 2,000 years, not 10,000.
- **Strobilanthus**: Known for a flowering cycle of 12 years, not applicable here.

7. **Conclusion**: The only option that fits the criteria of being a very old viable seed from the Arctic tundra that germinated after 10,000 years is **Lupinus arcticus**.

### Final Answer:
The seed is **Lupinus arcticus**.
