C. temperate region
D. coastal region

Answer

**Step-by-Step Solution:**

1. **Identify the Options:** The question asks for the coldest region on Earth. The options provided are likely to include different climatic regions such as polar, tropical, temperate, and coastal.

2. **Analyze the Polar Region:**
- The polar region is characterized by extreme cold temperatures.
- It experiences six months of continuous daylight (midnight sun) and six months of darkness (polar night).
- The temperature in the polar region can drop to as low as -37 degrees Celsius.
- This region is predominantly covered with ice and snow.

3. **Evaluate Other Regions:**
- **Tropical Region:** This region is known for its hot and humid climate. Temperatures can reach up to 40 degrees Celsius in summer and drop to around 15 degrees Celsius in winter. Therefore, it cannot be the coldest region.
- **Temperate Region:** This region has moderate temperatures with warm summers and cold winters, but it is not as cold as the polar region.
- **Coastal Region:** The coastal region has a moderate climate due to the influence of the ocean, which keeps temperatures from becoming too extreme. Thus, it is also not the coldest.

4. **Conclusion:** Based on the analysis, the polar region is the coldest region on Earth.

**Final Answer:** The coldest region on Earth is the **polar region**.
