The correct answer is False.
Step-by-step explanation
The solar atmosphere is an outer layer of the sun, which, like the Earth's atmosphere, is composed of several gases at different levels. Particularly, the Atmosphere of the sun has 3 layers, the first is the photosphere, the second is the chromosphere and the third is the Corona. The first is what we can see from the Earth, the second is the layer that emits white light, and the third, we can not see it, however, its main feature is the high temperature it reaches. So it is false the chromosphere is not the hottest because the hottest is the Corona.
