Due to the fact that the universe is expanding, when light from other galaxies reaches Earth: D. it is red shifted.

What is a redshift?

A redshift refers to a shift (displacement) of the spectral lines of astronomical objects such as stars, galaxies, etc., toward longer wavelengths as a result of the Doppler effect. Also, the red end of an electromagnetic spectrum are characterized by longer wavelengths.

This ultimately implies that, a redshift occurs when observing a galaxy from planet Earth because the universe is expanding and the galaxy is moving away from planet Earth.

In conclusion, we can infer that light from distant galaxies most likely shows a red shift when it reaches planet Earth, which indicates that the universe is expanding.
