Correct Answer: Thermosphere
Solution : The answer is Thermosphere.
The thermosphere is the warmest region of the Earth's atmosphere and extends roughly 80 km above the mesosphere and below the exosphere. It is distinguished by extraordinarily high temperatures. The thermosphere's high temperatures are caused by the absorption of strong ultraviolet (UV) and X-ray radiation from the sun.
