A newly discovered star is classified as an M-type star. Based on the H-R diagram, what is most likely true about this star?

M-type stars are at the cool end of the stellar classification sequence, so their surfaces are cooler than the Sun’s and they appear red. They are generally cooler and less luminous than the hot, blue stars described in choice C, and they do not typically end as supernovae. Therefore, “It is cooler than the Sun and likely red in color” is the best choice.
