b.Polaris

c. Aldebran

e. The Sun

Explanation:

arent sure

In comparison with the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are: cooler and less luminous.

A star is a giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force.

Generally, a star typically comprises two (2) main hot gases and these are:  

I. Hydrogen (H).

II. Helium (He).

Main sequence refer to stars that can fuse hydrogen atoms in its core, to form helium atoms.

Some examples of a main sequence include the following;  

Sun (closest to planet Earth). Antares. Canopus. Vega. Betelgeus.

The luminosity of a star can be defined as the total amount of light radiated by the star per second. Also, it is measured in Watts (W).

In conclusion, smaller stars in the main sequence are cooler and less luminous than massive stars in the main sequence.
