Answer

To solve the question about the non-obligate category introduced between class and division, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taxonomic Hierarchy**:
- The taxonomic hierarchy consists of several levels, including kingdom, phylum (or division), class, order, family, genus, and species. Each level represents a rank in the classification of organisms.

2. **Identify Obligatory and Non-Obligatory Categories**:
- Obligatory categories are essential for classification, while non-obligatory categories are additional classifications that can be used but are not required.

3. **Determine the Position of the Categories**:
- The question asks for a non-obligate category that is positioned between class and division.
- The hierarchy shows that between division and class, there can be additional categories.

4. **Evaluate the Options**:
- **Tribe**: This is a non-obligate category that exists between family and genus.
- **Subclass**: This is a non-obligate category that exists below class.
- **Superclass**: This is a non-obligate category that exists above class and below division.
- **Taxon**: This is a general term that refers to any group in the classification hierarchy.

5. **Select the Correct Answer**:
- The correct answer is **superclass**, as it is the non-obligate category that is introduced between division and class.

### Final Answer:
The non-obligate category introduced between class and division is **superclass** (Option 3).
