Larger Stars Have More Thermonuclear "Fuel

Larger stars have more thermonuclear "fuel":

A) and, since all nuclear reactions proceed at the same rate, they live longer than smaller stars which have less fuel.
B) but they also consume their fuel at a larger rate and thus live the same length of time as smaller stars, which have less fuel but consume it more slowly.
C) but they also consume their fuel at a larger rate and thus live the a shorter time than smaller stars, which have less fuel but consume it more slowly.
D) but there is no correlation between the size of a star and its lifetime.
