If the sun is white-yellow, which of the following is a reasonable approximation of its temperature? a. 4,923 k b. 7,489 k c. 6,232 k d. 5,778 k

I think the correct answer from the choices listed above is option D. If the Sun is white-yellow, then a reasonable approximation of its temperature would be 5778 K. The Sun has a surface temperature of about 5,800 Kelvin. Because of this temperature, the bulk of the light we see streaming from the Sun is yellow/white.

Solubility would be your answer.
