c. They will be shifted toward the red end of the spectrum.

Explanation:

When the absorption or emission lines of a moving object away from from the earth at very high speed then the spectral lines will be shifted toward the red end of the spectrum. This effect can be easily understand by Doppler effect ...

So the our option c is correct.

c. They will be shifted toward the red end of the spectrum.
