C. dye stuffs
D. All the above.

Answer

To solve the question regarding the chromatography technique and its applications, we can break down the answer step by step:

### Step-by-Step Solution:

1. **Understanding Chromatography**:
- Chromatography is a separation technique used to separate components of a mixture based on their different interactions with a stationary phase and a mobile phase.

2. **Analyzing the Options**:
- **Option A: Small sample of mixtures**: Chromatography can indeed be used to separate small samples of mixtures.
- **Option B: Plant pigments**: Chromatography is commonly used to separate plant pigments, such as chlorophyll and carotenoids.
- **Option C: Dyes**: Chromatography is also used to separate various dyes, which can be found in inks and other colorants.
- **Option D: All of the above**: Since chromatography can be used for all the options mentioned (small samples of mixtures, plant pigments, and dyes), this option seems to be the most comprehensive.

3. **Conclusion**:
- Since chromatography is applicable to all the mentioned categories, the correct answer is **Option D: All of the above**.

### Final Answer:
The chromatography technique is used for the separation of **all of the above** (small sample of mixtures, plant pigments, and dyes).
