Options

A. Tips of shoot
B. Root
C. Stem
D. Lateral buds and leaves

Answer

**Step-by-Step Solution:**

1. **Understanding Cytokinins**: Cytokinins are a type of plant hormone known as plant growth regulators. They play a crucial role in regulating various aspects of plant growth and development.

2. **Classification of Plant Hormones**: Plant hormones can be categorized into two groups:
- Plant growth promoters (like cytokinins, auxins, and gibberellins) which promote growth.
- Plant growth inhibitors (like abscisic acid) which inhibit growth, especially under stress conditions.

3. **Function of Cytokinins**: Cytokinins are primarily involved in promoting cell division, cell enlargement, flowering, and fruiting activities in plants.

4. **Sources of Cytokinins**: The primary site of cytokinins production in plants is the roots. They are synthesized mainly in the root tissues and then transported to other parts of the plant.

5. **Conclusion**: Based on the information gathered, the correct answer to the question "Cytokinins are formed primarily in which area of the plant?" is that cytokinins are primarily formed in the roots of the plant.

**Final Answer**: Cytokinins are primarily formed in the roots of the plant.
