Option B

A B star is a large, luminous, blue-white star of spectral type B with a surface temperature of 10,200 to 30,000°C. These stars have from 2 to 16 times the mass of the Sun and these type stars are extremely luminous and blue. Since option B shows a blue color that is why we can say that this is the correct choice.
