In artificial system, the organisms are classified on the basis of

Options

A. All the possible characters
B. Phylogenetic trends
C. A few characters
D. Anatomical, cytological and biochemical traits alongwith morphological traits.

Answer

### Step-by-Step Solution

1. **Understanding Classification**:
- Classification is the process of grouping living organisms based on shared characteristics.
- It involves several taxonomic levels: kingdom, phylum, class, order, family, genus, and species.

**Hint**: Remember that classification helps organize biological diversity into manageable categories.

2. **Types of Classification**:
- There are three main types of classification: artificial, natural, and phylogenetic.
- Each type uses different criteria for grouping organisms.

**Hint**: Think about how different classification systems might focus on different traits or characteristics of organisms.

3. **Defining Artificial Classification**:
- Artificial classification groups organisms based on non-evolutionary features.
- It often relies on a limited number of observable traits, such as the number and arrangement of reproductive structures (like stamens and styles in plants).

**Hint**: Focus on the idea that artificial classification does not consider evolutionary relationships.

4. **Analyzing the Options**:
- **Option 1**: "All the possible characters" - This is incorrect because artificial classification does not consider all traits.
- **Option 2**: "Phylogenetic traits" - This is incorrect as phylogenetic traits relate to evolutionary relationships, not artificial classification.
- **Option 3**: "A few characters" - This is correct as artificial classification is based on a limited number of traits.
- **Option 4**: "Anatomical, cytological and biochemical traits along with morphological traits" - This is incorrect as these traits are more aligned with natural classification.

**Hint**: Evaluate each option based on the definition of artificial classification.

5. **Conclusion**:
- The correct answer is **Option 3: a few characters**. In artificial classification, organisms are classified based on a limited set of observable traits rather than their evolutionary history.

**Hint**: Summarize the key points about artificial classification to reinforce your understanding.
