Solution
The correct option is C Both statements are correct
As other stars can be bigger or smaller than the sun, to have a proper reference, the mass of the sun is used as a unit of mass. Therefore, the masses of other stars are measured with respect to the mass of the sun.
Stars with lower mass use their fuel at a slower rate and live longer. Whereas high-mass stars use their fuel at a much faster rate, because of which they evolve quickly and die faster.
Hence, both statements are correct.
