Main Sequence
There are seven main stellar classifications, which are O, B, A, F, G, K, and M. These classifications are based on the surface temperature of stars, with O being the hottest and M being the coolest. Each classification is further divided into subclasses denoted by a number from 0 to 9.
The correct classification for the stars is O,B,A,F,G,M,K.
