The answer is C where the star is found in the sky. If a star is moving toward us, its spectroscopy will be observed at shorter wavelengths, this is called "blueshifted". If the star is moving away from us, the lines will appear in longer wavelengths, and that's called "redshifted". 
Sorry for a late response, but I hope this helped.
