All given are suffixes used for category class, except

Options

A. `-"phyta"`
B. `-"opsida"`
C. `-"phyceae"`
D. `-"ae"`

Answer

To solve the question regarding which of the given suffixes is not used for category class, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Suffixes**: The suffixes provided in the question are FITA, OPSIDA, FIAC, and ZAE.

2. **Understand the Context**: In biological classification, suffixes are often used to denote different taxonomic ranks. Specifically, we are looking for suffixes that are used for the class category.

3. **Analyze Each Suffix**:
- **FITA**: This suffix is seen in terms like "Bryophyta," which refers to a division (or phylum) in the plant kingdom, not a class. Thus, it is not used for class.
- **OPSIDA**: This suffix is used in terms like "Lycopsida," which refers to a class of plants.
- **FIAC**: This suffix is less common but can be associated with certain classes in biological classification.
- **ZAE**: This suffix is used in terms like "Monocotyledonae," which refers to a class of flowering plants.

4. **Conclusion**: Since FITA is used for a division (phylum) and not for a class, it is the correct answer to the question. The other suffixes (OPSIDA, FIAC, ZAE) are associated with classes.

### Final Answer:
The suffix that is not used for category class is **FITA**.
