Answer 2

Answer:

a. Blue.

Explanation:

Hello,

Giant blues have moderate increase in size and luminosity compared to main-sequence stars of the same mass or temperature, and are hot enough to be called blue, meaning spectral class O, B, and sometimes early A. They have temperatures from around 10,000 K which are by far, higher than red, white and yellow stars.
