Astar with a surface temperature between 5,000 k and 6,000 k appears blue yellow red white

Option B, yellow stars

Explanation:

The different range of temperature and the color associated with the stars are as follows - Star with temperature between 5 to 6 thousand kelvin are yellow in color . A star of blue color has a temperature between 30 to 40 thousand kelvin, while a star that has a temperature between 10 to 30 thousand kelvin appears blue white in color. A star appears white when it has a temperature between 7 to 10 Kelvin . A star has red color when its temperature is less than 3.5 thousand kelvin.

Hence, option B is correct.

the denominator has a very specific role.
