Options

A. reproductive parts are more conservative
B. flowers can be safely preserved
C. flowers are nice to work with
D. flowers have various colours and scents.

Answer

To answer the question "Floral features are commonly used for identification of angiosperms because," we can analyze the provided options and determine the most appropriate reason.

### Step-by-Step Solution:

1. **Understand the Importance of Floral Features**: Floral features, including the structure and characteristics of flowers, are critical for the classification and identification of angiosperms (flowering plants).

2. **Evaluate the Options**:
- **Option 1**: Reproductive parts are more conservative.
- This suggests that the reproductive structures (like stamens and carpels) show less variation among species, making them reliable for identification.
- **Option 2**: Flowers can be safely preserved.
- While preservation is important, it does not directly relate to the identification process.
- **Option 3**: Flowers are nice to work with.
- This is subjective and does not provide a scientific basis for identification.
- **Option 4**: Flowers have various colors and scents.
- While colors and scents can vary, they are not consistent enough for reliable identification.

3. **Identify the Correct Option**: After evaluating the options, it is clear that the first option, "reproductive parts are more conservative," is the most accurate reason for why floral features are commonly used for the identification of angiosperms. This is because the reproductive structures tend to remain relatively unchanged across different species, allowing for more accurate classification.

4. **Conclusion**: Therefore, the correct answer is that floral features are commonly used for identification of angiosperms because the reproductive parts are more conservative.

### Final Answer:
Floral features are commonly used for identification of angiosperms because reproductive parts are more conservative.
