A Correct answer
Explanation

The ionosphere is the layer of Earth's atmosphere that contains ions and free electrons, making it reflective to radio waves. This property is crucial for long-distance radio communication, as radio waves bounce off this layer back to Earth's surface rather than passing through to space.
