D. all

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of the Large Intestine**: The large intestine, also known as the colon, plays a crucial role in the digestive system, primarily focusing on the absorption of certain substances rather than digestion.

2. **Absorption of Water**: One of the primary functions of the large intestine is the absorption of water. As the undigested food material passes through the large intestine, water is reabsorbed, which helps in forming solid waste (feces).

3. **Absorption of Minerals**: The large intestine is also involved in the absorption of various minerals, such as sodium and potassium, which are essential for maintaining electrolyte balance in the body.

4. **Absorption of Drugs**: Certain drugs can be absorbed in the large intestine. This is particularly relevant for medications that are designed to be taken orally and can be absorbed in the intestinal tract.

5. **Conclusion**: Given that the large intestine is involved in the absorption of water, minerals, and certain drugs, we can conclude that the correct answer to the question is D: All of the above.

**Final Answer**: D. All of the above.
