D. Kidneys .

Answer

**Step-by-Step Solution:**

1. **Understanding Pleurisy**: Pleurisy is a medical condition that involves inflammation of the pleura, which are the membranes surrounding the lungs.

2. **Identifying the Location of the Pleura**: The pleura consists of two layers: one layer is attached to the lungs, and the other is attached to the chest wall. The space between these two layers is called the pleural space.

3. **Function of the Pleura**: The pleura allows the lungs to expand and contract smoothly during breathing. Normally, there is a small amount of fluid in the pleural space that facilitates this movement.

4. **Effects of Pleurisy**: In pleurisy, the pleural membranes become inflamed, causing them to swell. This inflammation leads to friction between the two layers when breathing, resulting in sharp chest pain, especially during inhalation and exhalation.

5. **Conclusion**: Since pleurisy affects the pleura, which is associated with the lungs, we conclude that pleurisy is a disease of the lungs.

**Final Answer**: Pleurisy is the disease of the lungs.
