Answer

To solve the question "In the system of classification, which one of the following is NOT a family or order?", we need to analyze each option provided:

### Step-by-Step Solution:

1. **Understanding the Classification System**: The biological classification system is hierarchical and includes several levels: Kingdom, Phylum (or Division), Class, Order, Family, Genus, and Species. We need to identify which of the given options does not fit into the categories of family or order.

2. **Analyzing the Options**:
- **Option 1: Chlorophyta**: This term refers to a division (or phylum) of green algae. It is not a family or an order.
- **Option 2: Leguminosae**: This is a family name, specifically for leguminous plants (now often referred to as Fabaceae). Therefore, it is a family.
- **Option 3: Angiospermae**: This term refers to a class or division of flowering plants. It is not classified as a family or an order.
- **Option 4: Pindales**: This is an order within the angiosperms, specifically referring to certain flowering plants.

3. **Identifying the Correct Answer**:
- From the analysis, both Chlorophyta and Angiospermae do not belong to the categories of family or order. However, Angiospermae is classified as a class or division, while Chlorophyta is a division of algae.
- Leguminosae is a family, and Pindales is an order.

4. **Conclusion**: Since the question asks for the option that is neither a family nor an order, the correct answer is **Angiospermae**.

### Final Answer:
**Angiospermae** (Option 3) is NOT a family or order.
