Options

A. Biological names are generally in Greek and written in italics
B. Family comprises a group of related species which has more characters in common
C. Triticum aestivum comes under the order sapindales
D. Families like convolvulaceae and solanaceae are included in the order polymoniales mainly based on floral characters.

Answer

To solve the question of selecting the correct statement regarding biological classification, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement**:
- The statement claims that "Biological names are generally in Greek and written in Italian."
- **Evaluation**: Biological names are primarily in Latin, not Greek. Additionally, they are italicized, not written in Italian.
- **Conclusion**: This statement is incorrect.

2. **Analyze the Second Statement**:
- The statement claims that "family comprises a group of related species which has more characters in common."
- **Evaluation**: While a family does comprise related species, it is not accurate to say it has "more characters in common" than other taxonomic ranks. The family is an intermediate rank that includes genera and species.
- **Conclusion**: This statement is also incorrect.

3. **Analyze the Third Statement**:
- The statement claims that "Triticum aestivum comes under the order of spindles."
- **Evaluation**: Triticum aestivum is commonly known as wheat and belongs to the order Poales, not "spindles."
- **Conclusion**: This statement is incorrect.

4. **Analyze the Fourth Statement**:
- The statement claims that "families like Convolvulaceae and Solanaceae are included in the order of Polymoniales mainly based on the floral characteristics."
- **Evaluation**: This statement is accurate. Families such as Convolvulaceae and Solanaceae are indeed classified under the order Polymoniales, and this classification is primarily based on floral characteristics.
- **Conclusion**: This statement is correct.

### Final Answer:
The correct statement is: **"Families like Convolvulaceae and Solanaceae are included in the order of Polymoniales mainly based on the floral characteristics."**
