Vernalisation is seen in

Options

A. Sugarbeet
B. Carrot
C. Cabbage
D. All the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Vernalization**: Vernalization is a process that involves exposing young plants to cold temperatures (winter conditions) to induce flowering. This adaptation allows certain plants to synchronize their flowering with favorable conditions for reproduction.

2. **Identifying the Key Plants**: The question asks in which plants vernalization is observed. The options provided are sugar beet, carrot, cabbage, and "all of the above."

3. **Analyzing Each Option**:
- **Sugar Beet**: This plant is known to require a period of cold exposure to flower effectively.
- **Carrot**: Carrots also benefit from vernalization, as cold temperatures can enhance their flowering process.
- **Cabbage**: Cabbage is another plant that responds positively to cold exposure, leading to earlier flowering.

4. **Conclusion**: Since all three plants (sugar beet, carrot, and cabbage) are known to undergo vernalization, the correct answer is that vernalization is seen in "all of the above."

5. **Final Answer**: The answer to the question is "all of the above."
