Answer

### Step-by-Step Solution:

1. **Understanding Pappus**: The term "pappus" refers to a modified structure found in certain flowering plants, particularly in the family Asteraceae (the daisy family). It is typically associated with the calyx of the flower.

2. **Identifying the Options**: The options given are:
- A) Bracts
- B) Bractioles
- C) Corolla
- D) Calyx

3. **Analyzing Each Option**:
- **Bracts**: These are modified leaves that are often found at the base of a flower or inflorescence. They do not relate to the pappus.
- **Bractioles**: These are small bracts that are associated with a flower or inflorescence but are not related to the pappus.
- **Corolla**: This is the collective term for the petals of a flower. The pappus is not a modification of the corolla.
- **Calyx**: The calyx is the outermost whorl of a flower, composed of sepals. In some plants, the calyx can be modified into a pappus, which aids in seed dispersal.

4. **Conclusion**: Since the pappus is a modification of the calyx, the correct answer is option D) Calyx.

### Final Answer:
The pappus is a modification of the **Calyx** (Option D).
