Options

A. one or two morphological characters
B. few characters
C. several characters
D. synthetic characters

Answer

**Step-by-Step Solution:**

1. **Understanding Artificial Classification**: The artificial system of classification is a method used to categorize organisms based on specific characteristics rather than evolutionary relationships.

2. **Morphological Characters**: This system primarily relies on morphological characters, which are the physical traits of organisms, such as structure, form, and appearance.

3. **Number of Characters Used**: The artificial classification system typically uses one or two morphological characters to classify organisms. This is in contrast to other systems that may use a broader range of characteristics.

4. **Historical Context**: The artificial system was notably proposed by Theophrastus, who classified plants based on simple traits, such as height, dividing them into categories like herbs, shrubs, and trees.

5. **Conclusion**: Therefore, the correct answer to the question "Artificial system is based on" is that it is based on one or two morphological characters.

**Final Answer**: The artificial system is based on one or two morphological characters.
