Which of the following is not associated with growth of plant?

Options

A. Auxin
B. Gibberellins
C. Cytokinins
D. Abscisic acid

Explanation

To determine which of the following options is not associated with the growth of plants, we need to analyze the provided options: auxin, gibberellin, cytokinin, and abscisic acid.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Auxin
- B) Gibberellin
- C) Cytokinin
- D) Abscisic Acid

2. **Understand Plant Hormones**: All four options are classified as plant hormones, also known as phytohormones.

3. **Analyze Each Hormone**:
- **Auxin**: This hormone is known to promote cell elongation and is involved in various growth processes in plants.
- **Gibberellin**: This hormone also promotes growth, particularly in stem elongation and seed germination.
- **Cytokinin**: This hormone promotes cell division and growth in plants.
- **Abscisic Acid**: This hormone is known for its role in inhibiting growth. It helps in the dormancy of seeds and is involved in stress responses.

4. **Determine the Growth Association**:
- Auxin, gibberellin, and cytokinin are all growth-promoting hormones.
- Abscisic acid, on the other hand, is an inhibitory hormone that does not promote growth.

5. **Conclusion**: Based on the analysis, the hormone that is not associated with the growth of plants is **D) Abscisic Acid**.

### Final Answer:
The correct answer is **D) Abscisic Acid**.
