Options

A. Thermosphere
B. Stratosphere
C. Mesosphere
D. Lithosphere

Answer

### Step-by-Step Solution:

1. **Understanding Atmospheric Layers**: The Earth's atmosphere is divided into several layers, each with distinct characteristics. The main layers from the surface of the Earth upward are:
- Troposphere
- Stratosphere
- Mesosphere
- Thermosphere
- Exosphere

2. **Identifying the Ozone Layer**: The ozone layer is a region of the atmosphere that contains a high concentration of ozone (O₃) molecules. It plays a crucial role in absorbing the majority of the sun's harmful ultraviolet radiation.

3. **Locating the Ozone Layer**: The ozone layer is specifically located within the **stratosphere**, which is the second layer of the atmosphere, situated above the troposphere.

4. **Conclusion**: Therefore, the ozone layer exists in the **stratosphere**.

### Final Answer:
The ozone layer exists in the **stratosphere**.
