Traumatin is

Options

A. Auxin
B. Gibberellin
C. Cytokinin
D. Abscisic acid.

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about "Traumatin" and its classification among the given options: auxin, gibberellin, cytokinin, and abscisic acid.

2. **Identify the Nature of Traumatin**: Traumatin is a plant hormone that is secreted in response to wound or injury in plants. It plays a role in the plant's response to damage.

3. **Determine the Function of Traumatin**: Traumatin is known to stimulate cell division. This is crucial for the plant to heal and regenerate tissues after an injury.

4. **Analyze the Options**:
- **Auxin**: Primarily promotes cell differentiation and elongation, not specifically cell division.
- **Gibberellin**: Mainly involved in promoting flowering and shoot elongation.
- **Cytokinin**: Known to stimulate cell division and is often associated with promoting growth in young tissues.
- **Abscisic Acid**: Generally inhibits growth, promotes seed dormancy, and causes stomatal closure.

5. **Match Traumatin with the Correct Option**: Since Traumatin stimulates cell division and is involved in the plant's response to wounding, it aligns with the function of cytokinin.

6. **Conclusion**: Based on the analysis, the correct answer is **cytokinin**.

**Final Answer**: Traumatin is a cytokinin.
