C. `9.754 km`
D. `11.034 km`.

Answer

To find the depth of Challenger Deep in the Mariana Trench, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Location**:
- Challenger Deep is located in the Mariana Trench, which is situated in the Western Pacific Ocean.

2. **Understand the Depth Measurement**:
- The depth of Challenger Deep is often measured in feet and meters.

3. **Convert Depth from Feet to Meters**:
- The depth of Challenger Deep is approximately 36,200 feet. To convert this to meters, we use the conversion factor where 1 foot is approximately 0.3048 meters.
- Calculation:
\[ 36,200 \text{ feet} \times 0.3048 \text{ meters/foot} \approx 10,973 \text{ meters} \]

4. **Convert Meters to Kilometers**:
- Since 1 kilometer is equal to 1,000 meters, we convert the depth in meters to kilometers.
- Calculation:
\[ 10,973 \text{ meters} \div 1,000 \approx 10.973 \text{ kilometers} \]

5. **Select the Closest Option**:
- The options provided are:
1. 4.7 km
2. 6.056 km
3. 9.754 km
4. 11.034 km
- The closest value to 10.973 kilometers is 11.034 kilometers.

6. **Conclusion**:
- Therefore, the depth of Challenger Deep in the Mariana Trench is approximately **11.034 kilometers**.
