The ionosphere useful for radio communication is mainly linked with which region?
Answer and explanation
Correct answer: Thermosphere
The ionosphere is an electrically charged region of the upper atmosphere and is mainly associated with the thermosphere, although it can overlap other upper layers. Free electrons and ions can reflect or refract certain radio waves, allowing signals to travel beyond the horizon. Therefore, option B is correct; the troposphere and stratosphere are lower layers, while a dust layer is not a standard atmospheric region.
