B. C→B→D→E→G
C. A→B→D→E→F

本题详细解析:
Explanation:
Since the mass of the star is greater than the Sun, its luminosity should be higher. Therefore, its position on the main sequence should be A instead of C, where C represents the Sun. Moreover, the last stage of the evolution should be white dwarf which is labelled as G.
