Answer

To solve the question "Suffix is not used for:-", we need to analyze the options provided and understand the context of suffixes in biological classification.

### Step-by-Step Solution:

1. **Understanding Taxonomic Ranks**: In biological classification, organisms are categorized into different ranks such as kingdom, phylum (or division), class, order, family, genus, and species.

2. **Identifying Suffix Usage**:
- **Genus**: Generally, there is no specific suffix used for the genus. The names of genera are often derived from various sources and do not follow a strict suffix rule.
- **Species**: Similar to genus, species names do not have a specific suffix. They can be derived from various languages and do not adhere to a fixed suffix pattern.
- **Kingdom**: Kingdom names also do not have a specific suffix. They are broad categories and do not follow a suffix rule.

3. **Recognizing Where Suffixes Are Used**:
- **Family**: In the plant kingdom, family names often end with the suffix "-aceae" (e.g., Rosaceae for the rose family).
- **Order**: Order names can have various suffixes, such as "-ales" (e.g., Rosales).
- **Division**: In plants, division names often end with the suffix "-phyta" (e.g., Angiospermae).

4. **Conclusion**: Since suffixes are not used in the genus, species, and kingdom, we can conclude that the correct answer to the question is option number four: "all of them".

### Final Answer:
The suffix is not used for: **All of them (option 4)**.
