That it is coming toward you.Red shift means it is going away.Blue shift means it is coming closer so B.Hope this helps.
Give me brainliest and stars.

The stars and the earth are part of the solar system and are located at a specific distance. If the star exhibits a blue shift, then the distance is decreasing. Thus, option b is correct.

What is blueshift?

Blueshift is a shift that occurs in the wavelength in the blue region of the light spectrum that leads to the moving of the object towards another object.

The blue and red shifts are used by astronomers to study the distance and the motion of the objects in space. The redshift causes the object to move far away while blue causes it to move towards.

Therefore, the blueshift causes the distance between the earth and the star to reduce.
