Identify the substance which is an adenine derivative compound.

Options

A. auxin
B. gibberellins
C. cytokinin
D. ABA

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks to identify a substance that is an adenine derivative compound among the given options: Oxin, Zeberlin, Cytokinin, and ABA.

2. **Identifying Adenine**: Adenine is a nitrogenous base that belongs to the purine family. It is a key component of nucleic acids like DNA and RNA.

3. **Analyzing the Options**:
- **Oxin**: This is primarily involved in apical dominance and is not derived from adenine.
- **Zeberlin**: This hormone is related to germination and growth but is not derived from adenine.
- **Cytokinin**: This is known to be a derivative of adenine. Specifically, it is synthesized from adenine and plays a crucial role in promoting cell division (cytokinesis).
- **ABA (Abscisic Acid)**: This is a stress hormone and does not derive from adenine.

4. **Conclusion**: Among the options provided, Cytokinin is the substance that is an adenine derivative compound.

5. **Final Answer**: The substance which is an adenine derivative compound is **Cytokinin**.
