Answer

To solve the question "Which one of the following is not a category?", we need to analyze the options provided and identify which one does not belong to the taxonomic categories.

1. **Identify the Options**: The options given are likely to include terms related to biological classification. Common taxonomic categories include kingdom, phylum, class, order, family, genus, and species.

2. **Evaluate Each Option**:
- **Option 1: Phylum** - This is a recognized taxonomic category that groups together organisms based on certain similarities. Therefore, it is a category.
- **Option 2: Genus** - This is also a recognized taxonomic category that groups species that are closely related. Thus, it is a category.
- **Option 3: Class** - This is another recognized taxonomic category that groups related orders. Hence, it is a category.
- **Option 4: Poesy** - This term refers to a family of grasses and is not a recognized taxonomic category in the same way as phylum, genus, or class.

3. **Conclusion**: Since phylum, genus, and class are all recognized taxonomic categories, the only term that does not fit this classification is "Poesy". Therefore, the correct answer to the question is option 4.

**Final Answer**: Poesy is not a taxonomic category.
