If dust particles are high in the atmosphere, why can sunset redness become more distinct?
Answer and explanation
Correct answer: Because particles affect the scattering of light
At sunset, sunlight travels through a longer path in the atmosphere. Dust and other aerosols scatter and sometimes absorb shorter wavelengths more strongly, allowing relatively more red and orange light to reach an observer. This can intensify the sunset colour, although the exact appearance depends on particle size and composition. Thus D is correct; A, B and C have no optical basis.
