Which layer is associated with communication because of ionized regions in the upper atmosphere?
Answer and explanation
Correct answer: Thermosphere
The governing concept is ionization by energetic solar radiation. The ionosphere is a region of charged particles that overlaps mainly the thermosphere and can reflect or refract certain radio waves, supporting long-distance communication. Therefore option D is the intended answer. The troposphere affects some radio propagation through weather, but it is not the ionized upper region described; the stratosphere and mesosphere are not the best match.
