Which of the following disease is not caused by RNA virus?

Options

A. Measles
B. Dengue
C. Poliomyelitis
D. Chicken pox

Answer

To determine which disease is not caused by an RNA virus, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the diseases and their causative agents**:
- **Measles**: Caused by the measles virus (MEV).
- **Dengue**: Caused by the dengue virus.
- **Poliomyelitis**: Caused by the poliovirus.
- **Chicken Pox**: Caused by the Varicella zoster virus.

2. **Examine the genetic material of each virus**:
- **Measles Virus**: The genetic material is single-stranded RNA (ssRNA).
- **Dengue Virus**: The genetic material is also single-stranded RNA (ssRNA).
- **Poliovirus**: The genetic material is single-stranded RNA (ssRNA).
- **Varicella Zoster Virus (Chicken Pox)**: The genetic material is DNA.

3. **Determine which disease is not caused by an RNA virus**:
- Measles, Dengue, and Poliomyelitis are all caused by viruses that have RNA as their genetic material.
- Chicken Pox is caused by the Varicella zoster virus, which has DNA as its genetic material.

4. **Conclusion**: The disease that is not caused by an RNA virus is **Chicken Pox**.

### Final Answer:
**Chicken Pox** is the disease that is not caused by an RNA virus.
