D. buffer

Answer

To answer the question about the nature of all gibberellins, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Gibberellins**:
- Gibberellins are a class of plant hormones that play a crucial role in various plant processes such as seed germination, flowering, and stem elongation.

2. **Identifying the Options**:
- The options provided are:
1. Alkaline
2. Neutral
3. Acidic
4. Buffer

3. **Analyzing pH Levels**:
- To determine the nature of gibberellins, we need to understand the definitions of the terms related to pH:
- **Acidic**: pH less than 7
- **Neutral**: pH equal to 7
- **Alkaline (Basic)**: pH greater than 7
- **Buffer**: Solutions that resist changes in pH.

4. **Determining the Nature of Gibberellins**:
- Gibberellins are known to be acidic in nature. This is why they are often referred to as gibberellic acid (GA), where "G" stands for gibberellic and "A" stands for acid.

5. **Conclusion**:
