C. (a), (c) & (d)
D. (a), (b), (c) & (d)

Answer

To solve the question regarding the artificial system of classification, we will analyze each statement provided and determine if they are correct or not.

### Step-by-Step Solution:

1. **Statement (a)**: "Involves usage of one or few morphological characters for grouping of organisms."
- **Analysis**: The artificial system of classification indeed relies on a limited number of morphological characteristics to categorize organisms. This is a key feature of artificial classification systems.
- **Conclusion**: This statement is **correct**.

2. **Statement (b)**: "Aristotle used sexual characters as they are affected by environment."
- **Analysis**: Aristotle did classify organisms based on observable traits, including sexual characteristics. However, he did not specifically focus on sexual characters being affected by the environment in his classification. His classifications were more general and based on simple observable traits.
- **Conclusion**: This statement is **incorrect**.

3. **Statement (c)**: "Linnaeus gave sexual system of classification."
- **Analysis**: Carl Linnaeus is well-known for developing a sexual system of classification based on the number and arrangement of reproductive organs in plants. He categorized plants into classes based on these sexual characteristics.
- **Conclusion**: This statement is **correct**.

4. **Statement (d)**: "Gave equal weightage to vegetative and sexual characteristics."
- **Analysis**: The artificial system of classification primarily emphasizes morphological characteristics, particularly sexual characteristics, rather than giving equal weight to vegetative traits. Thus, it does not give equal importance to both types of characteristics.
- **Conclusion**: This statement is **incorrect**.

### Final Evaluation:
- Correct Statements: (a) and (c)
- Incorrect Statements: (b) and (d)

### Correct Option:
Based on the analysis, the correct statements are (a) and (c). Therefore, the correct answer would be the option that includes these statements.
