4. **Evaluating the Options:**
- Now, let's analyze the options given in the question:
- A) Induce cell division and inhibit aging - **This is correct.**
- B) Maintain dormancy - **Incorrect.**
- C) Induce flowering - **Incorrect.**
- D) Inhibit cell division - **Incorrect.**

5. **Conclusion:**
- Based on the functions of cytokinins, the correct answer is that they **induce cell division and inhibit aging**.

**Final Answer:**
The correct option for cytokinins is: **A) Induce cell division and inhibit aging.**
