In an artificial system of classification

Options

A. A large number of characters are taken into consideration
B. Correlated characters are more important
C. Physiological characters are relied upon
D. One or a few morphological characters are considered.

Answer

**Step-by-Step Solution:**

1. **Understanding Artificial Classification**:
- Artificial classification is a system that categorizes organisms based on specific characteristics rather than evolutionary relationships. It often focuses on observable traits.

2. **Identifying Key Characteristics**:
- In artificial classification, a limited number of morphological (physical) traits are used to classify organisms. This can include features like the number of stamens, styles, and stigmas in plants.

3. **Comparison with Other Classification Systems**:
- Unlike natural classification systems that consider a wide range of evolutionary and genetic traits, artificial systems prioritize a few distinct characteristics.

4. **Conclusion**:
- Therefore, the correct answer to the question about artificial classification is that it relies on "one or few morphological characters."

**Final Answer**: One or few morphological characters are considered in an artificial system of classification.
