Which of the following systems of classification involves usage of one or few morphological characters for grouping of organisms ?

Options

A. Artificial system
B. Natural system
C. Phylogenetic system
D. Bentham and Hooker's system

Answer

To determine which system of classification involves the usage of one or few morphological characters for grouping organisms, we can analyze the provided options: artificial system, phylogenetic system, and Bentham and Hooker system.

### Step-by-Step Solution:

1. **Understanding the Classification Systems**:
- **Artificial System**: This system groups organisms based on a limited number of characters, often focusing on a few morphological traits. The classification is not necessarily reflective of evolutionary relationships.
- **Natural System**: This system considers a broader range of characteristics, including reproductive and internal structures, to classify organisms based on their natural relationships.
- **Phylogenetic System**: This classification is based on the evolutionary relationships and genetic affinities among organisms, which involves a comprehensive analysis of various traits.

2. **Analyzing the Options**:
- **Artificial System**: As mentioned, it uses a few morphological characters for classification.
- **Natural System**: Involves multiple characters, not limited to just morphology.
- **Phylogenetic System**: Focuses on evolutionary relationships, which requires more than just a few morphological traits.

3. **Conclusion**:
- The system that primarily uses one or few morphological characters for grouping organisms is the **Artificial System** of classification.

### Final Answer:
The correct answer is the **Artificial System** of classification.
