In terms of the mass and lifetime of a star, which of these statements is true?
A) The mass of a star has no bearing on the length of a star's life or the speed of its evolution.
B) Stars of about 1 solar mass have the shortest lives; less massive stars evolve slowly and live a longer time, while more massive stars have long lives because of the large amount of fuel they contain.
C) The less massive the star, the shorter is its life because it has less hydrogen "fuel" to burn.
D) The more massive the star, the faster it evolves through its life.
