Which region plays an important role in reflecting radio waves?
Answer and explanation
Correct answer: Ionosphere
The ionosphere plays an important role in long-distance radio communication because it contains electrically charged particles, or ions and electrons. These particles can refract or reflect some radio waves back toward Earth, helping signals travel beyond the horizon. The other choices are atmospheric layers or boundaries without this principal communication function. Hence option A is correct.
