    sky?
    A Scattering of white light Correct Answer Incorrect Answer
    B Reflection of light from water bodies Correct Answer Incorrect Answer
    C Scattering of sunlight by air molecules Correct Answer Incorrect Answer
    D Absorption of blue light by the atmosphere Correct Answer Incorrect Answer

    Solution

    The sky appears blue primarily due to Rayleigh scattering. This phenomenon occurs when sunlight passes through the Earth's atmosphere, and the shorter wavelengths of light (like blue) are scattered in all directions by the molecules and small particles in the air. Since blue light is scattered more than other colors, the sky appears blue to us.
