Answer

To solve the question "Floral diagram does not show," we need to analyze the options provided and understand what a floral diagram typically represents.

### Step-by-Step Solution:

1. **Understanding Floral Diagrams**: Floral diagrams are graphical representations that depict the arrangement of floral parts in a flower. They typically illustrate the number, arrangement, and relationships of the various parts such as sepals, petals, stamens, and carpels.

2. **Analyzing the Options**:
- **Option A: Cohesion and Adhesion**: These terms refer to the fusion of similar parts (cohesion) and the fusion of different parts (adhesion). Floral diagrams can show these relationships, especially in cases where floral parts are fused, such as in the Fabaceae family.
- **Option B: Activation**: This term is not commonly associated with floral diagrams. Activation might refer to processes like pollination or fertilization, which are not depicted in floral diagrams.
- **Option C: Color and Shape of Petals**: Floral diagrams typically do not show the color and shape of petals; they focus on the arrangement and number of floral parts rather than their visual characteristics.
- **Option D: All of the Above**: This option suggests that all previous options are correct in stating what floral diagrams do not show.

3. **Conclusion**: Based on the analysis, floral diagrams do not depict the color and shape of petals. Therefore, the correct answer is **Option C**.

### Final Answer:
**Option C: Color and shape of petals**
