Solution
The answer is d) red shifted. This is based on the Doppler Effect, which states that an object moving away from the observer will have its light shifted towards the red end of the spectrum. This is because the wavelengths of light are stretched, which corresponds to a shift towards the red end of the spectrum. This is often used in astronomy to determine the speed and direction of distant objects.
