Correct Answer: 6371 km
Solution : The correct option is 6371 km.
The average radius of the Earth is approximately 6,371 kilometres. It's important to note that the Earth is not a perfect sphere; it's slightly flattened at the poles and bulging at the equator due to its rotation. As a result, there are different measurements for the equatorial radius and the polar radius, but the average value is commonly used for general calculations.
