Answer:

Option B

Explanation:

The seven stars are bigger in size as compared to the size of the sun. Also, these stars are more luminous as compared to sun. However, these stars appear small in size in comparison to sun because of their distance from earth. The larger is the distance, the dimmer is the star. Sun is at a distance of 0.0000158 Light years from Earth while the nearest star of the seven sister i.e Alpha Centauri is 4.37 light years away.

Hence, option B is correct
