Question

Quizplus · Accepted Answer

The common trait of all main-sequence stars is that they generate energy through hydrogen fusion in their core. This is a defining characteristic of main-sequence stars and distinguishes them from other types of stars. Option A is incorrect because main-sequence stars are not in the final stage of their lives, they are mid-life stars. Option B is incorrect because main-sequence stars can be of different spectral types, not just type G. Option D is incorrect because although main-sequence stars have a range of masses, they are all in a specific range that allows for hydrogen fusion in their cores.
