D. diphtheria

Answer

To solve the question regarding the disease characterized by the eruption of small red spots and inflammation of the nasal mucous membrane, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Symptoms**: The question mentions two key symptoms:
- Eruption of small red spots
- Inflammation of the nasal mucous membrane

2. **Consider Possible Diseases**: The options provided are:
- a. Chickenpox
- b. Measles
- c. Mumps
- d. Diphtheria

3. **Analyze Each Option**:
- **Chickenpox**: This disease is characterized by itchy red spots and blisters, but it does not typically cause inflammation of the nasal mucosa.
- **Measles**: This is a highly contagious viral infection that starts with symptoms like fever, cough, and runny nose. It is known for causing a red flat rash that begins on the face and spreads to the rest of the body. It also involves inflammation of the nasal mucosa.
- **Mumps**: This primarily affects the salivary glands and does not typically cause a rash or nasal inflammation.
- **Diphtheria**: This bacterial infection affects the throat and can cause a sore throat and fever, but it does not present with small red spots.

4. **Match Symptoms with Disease**: Based on the analysis, measles is the only disease that matches both symptoms: the eruption of small red spots (the characteristic rash) and the inflammation of the nasal mucous membrane.

5. **Conclusion**: Therefore, the disease characterized by the eruption of small red spots and inflammation of the nasal mucous membrane is **measles**.

### Final Answer:
The correct answer is **b. Measles**.
