B. Rises from `-2^(@)` to `92^(@)C`
C. Decreases from `-2^(@)` to `-15^(@)C`
D. Decreases from `-2^(@)` to `-92^(@)C`.

Answer

To answer the question regarding the temperature changes in the mesosphere, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Layers of the Atmosphere**:
- The Earth's atmosphere is divided into five major layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere. The mesosphere is the third layer.

2. **Identifying the Characteristics of the Mesosphere**:
- The mesosphere extends from about 50 km to 85 km above the Earth's surface.

3. **Temperature Variation in the Mesosphere**:
- In the mesosphere, the temperature decreases with increasing altitude. This is a key characteristic of this atmospheric layer.

4. **Specific Temperature Range**:
- The temperature in the mesosphere starts at approximately -2 degrees Celsius at the lower boundary and decreases to about -92 degrees Celsius at the upper boundary.

5. **Evaluating the Options**:
- Given the options:
- A) Rises from -2°C to 15°C
- B) Rises from -2°C to 92°C
- C) Decreases from -2°C to -15°C
- D) Decreases from -2°C to -92°C
- The correct option is D, as it accurately describes the temperature trend in the mesosphere.

### Final Answer:
The temperature in the mesosphere decreases from -2 degrees Celsius to -92 degrees Celsius.
