D Correct answer
Explanation

Red shift is caused by the Doppler effect or the expansion of the universe, where the wavelength of light is stretched. In contrast, the twinkling of stars, mirages, and rainbows are all phenomena caused by the refraction of light as it passes through different media. The term 'high' in the question is a typo for 'light'.
