These two diagrams contrast the habitable zones around the Sun and around a much lower mass star. They are shown to scale. Based on what you see here, what can you conclude about the possibility of finding life around the lower-mass star compared to finding life around a Sun-like star?
A) There is a higher probability that an orbiting planet will be in the habitable zone for a Sun-like star than for a lower-mass star. B) Sun-like stars must always have more life around them than lower-mass stars. C) A Sun-like star always has at least two habitable planets, while a lower-mass star may have only one habitable planet. D) There is virtually no chance of finding life around a lower-mass star.
