C. 500000 km
D. none of these

Answer

To express 5 cm in kilometers, we can follow these steps:

### Step 1: Convert centimeters to meters
We know that:
1 cm = 0.01 meters

To convert 5 cm to meters, we multiply:
5 cm = 5 × 0.01 meters

Calculating this gives:
5 cm = 0.05 meters

### Step 2: Convert meters to kilometers
Next, we know that:
1 meter = 0.001 kilometers

To convert 0.05 meters to kilometers, we multiply:
0.05 meters = 0.05 × 0.001 kilometers

Calculating this gives:
0.05 meters = 0.00005 kilometers

### Final Answer
Therefore, 5 cm is equal to:
- 0.05 meters
- 0.00005 kilometers
