Answer:
(A) Like all objects, the Sun emits thermal radiation with a spectrum that depends on its temperature, and the Sun's surface temperature is just right for emitting mostly visible light.
Explanation:
The temperature of an object is a direct measurement of the energy of motion that absorbs all of the radiation that it receives (that is, it does not reflect any light, nor but many objects (stars included) behave approximately like blackbodies. Therefore, based on the location or the composition of the object, such as the Sun, it emits a spectrum of visible light
