c) Sirius has a surface temperature and luminosity closest to Phecda

What is surface tension and luminosity of a star ?

Surface temperature is the temperature at or near a surface. Luminosity is an absolute measure of radiated electromagnetic power (light), the radiant power emitted by a light-emitting object over time.

As it can be observed from the graph attached that Sirius have a surface temperature of about 10,000 K which can be considered as closest to 9500 K comparatively to other stars and if we see the the y coordinate of Sirius which is the luminosity representing axis , then Sirius have a value of luminosity closer to 63

hence correct answer is c)Sirius
