Star A is blue-violet in color and has medium brightness (magnitude) when viewed from earth. Can you make any assumptions about the temperature, actual brightness, and distance from earth?
Star A is a hot star based on it's blue-violet color.
The actual brightness and distance can not be determined from the information that we have.
