Options

A. Indigestion
B. Vomiting
C. Constipation
D. Diarrhoea

Answer

To determine which disease is the result of the reflex action of the medulla oblongata, we need to analyze the functions of the medulla oblongata and the options provided.

### Step-by-Step Solution:

1. **Understand the Role of the Medulla Oblongata**:
- The medulla oblongata is a part of the brainstem that controls various autonomic functions. It is responsible for reflex actions such as respiration, heart rate regulation, and certain involuntary actions.

2. **Identify Reflex Actions Controlled by the Medulla**:
- Reflex actions that are controlled by the medulla oblongata include coughing, sneezing, swallowing, and vomiting. These actions are automatic responses to certain stimuli.

3. **Examine the Options Given**:
- The options provided are:
- Indigestion
- Vomiting
- Constipation
- Diarrhea

4. **Analyze Each Option**:
- **Indigestion**: This is a digestive issue that does not directly involve a reflex action of the medulla.
- **Vomiting**: This is a reflex action that is controlled by the medulla oblongata in response to certain stimuli (e.g., irritation of the stomach).
- **Constipation**: This is a digestive issue related to bowel movement and is not a reflex action.
- **Diarrhea**: This is also a digestive issue and does not involve a reflex action of the medulla.

5. **Conclusion**:
- Based on the analysis, the disease that is a result of the reflex action of the medulla oblongata is **vomiting**.

### Final Answer:
The correct answer is **vomiting**.
