Sunsets are a deep red because
A) tiny particles in the air are more efficient at scattering short wavelength light than they are at scattering long wavelength light. Hence, long wavelength light ends up coming directly towards you.
B) most polluting gases and dust particles in the air are reddish in color and lend their color to that of the sky.
C) air molecules absorb red light more efficiently than they do blue light because of their electron orbitals.
D) air molecules absorb blue light more efficiently than they do red light because of their electron orbitals.

Question

During sunset, the sun's light has to pass through more of the Earth's atmosphere, which scatters shorter wavelengths (blue and violet) more than longer wavelengths (red and orange). This scattering effect causes the sky to appear redder.
