The redshift of a star means that . the star is moving closer to the sun the star is moving the star is about to explode the star is getting farther away

D). The star is getting farther away.

Explanation:

As per the question, the redshift of a star implies that 'the star is moving farther away'. It is described as the modification or increase in light's wavelength due to experiencing electromagnetic radiation from a specific object. In this effect, the objects(in the space) move apart from each other as Hubble's law states the consequence of redshift i.e. leading to cause an increase in rate in their distance from the Earth. Thus, the redshift of a star imply that 'the stars are moving farther away from the planet. Hence, option D is the correct answer.
