The correct answer is option A. Stars vary greatly in temperature.

The temperatures of stars vary greatly. The temperature range for various stars exists between 3,000 Kelvin to 50,000 Kelvin. It means that a substantial difference of 47,000 Kelvin temperature may exist between two stars. We can easily compare temperatures of two stars by looking at their colors. A star with red color is cooler as compared to the one which has blue or white color. Not only color but also, mass of a star can give us an idea about its temperature. A larger star has more energy and therefore more temperature as compared to the one which is smaller in size.
