The stars appear higher in the sky than they actually are, due to:
(a) diffraction of light
(b) scattering of light
(c) refraction of light
(d) reflection of light

Solution

(c) refraction of light

The refraction of light changes the path of starlight, making stars appear higher in the sky than they actual are.
