A High-Mass Star Goes Through Many Fusion Cycles in Its

Multiple Choice

A high-mass star goes through many fusion cycles in its lifetime: hydrogen, helium, carbon, neon, oxygen, and silicon. How does the timescale for each cycle compare to the previous one?

A) Each new nucleus is heavier than the previous one, and thus it moves more slowly. Each successive stage therefore takes longer than the previous one.
B) The temperature is higher at each stage, and the number of nuclei to react is fewer. Thus, each stage takes a shorter time than the previous one.
C) 2 M to 8 M _{11efcd2d_508b_b449_b057_27538d845d54_TB7156_00} only
D) all stars 0.4 M _{11efcd2d_508b_b449_b057_27538d845d54_TB7156_00} to 8 M _{11efcd2d_508b_b449_b057_27538d845d54_TB7156_00}
