Two stars of the same surface temperature are compared, and one is found to have a radius 1000 times larger than the other. How would their luminosities compare?

    The larger one would have a luminosity 10 times larger than the smaller one.
     The larger one would have a luminosity 1000 times larger than the smaller one.
     The larger one would have a luminosity 100 times larger than the smaller one.
     The larger one would have a luminosity a million times larger than the smaller one.
     This is impossible, since the surface temperature of a star determines its radius.
