A. Chloroplast
B. Nucleus
C. Vacuole
D. Mitochondria

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a cell organelle that is shaped like a hollow sac and is responsible for storing substances such as food and water.

2. **Identifying the Options**: The options provided are:
- A) Chloroplast
- B) Nucleus
- C) Vacuole
- D) Mitochondria

3. **Analyzing Each Option**:
- **Chloroplast**: This organelle is involved in photosynthesis and contains chlorophyll. It is not primarily for storage.
- **Nucleus**: The nucleus is the control center of the cell, containing genetic material. It does not function as a storage sac.
- **Vacuole**: Vacuoles are indeed hollow sacs found in cells, especially in plant cells, and they store substances like food, water, and waste products.
- **Mitochondria**: These are the powerhouses of the cell, responsible for energy production, not for storage.

4. **Conclusion**: Based on the analysis, the organelle that fits the description of being a hollow sac for storage is the **Vacuole**.

5. **Final Answer**: The correct answer is **C) Vacuole**.
