explain this one

Dear Student, As the sunlight pass through the atmosphere, the longer wavelengths pass straight through. However, the shorter wavelength light is absorbed by the particles in the atmosphere. The absorbed blue light is radiated in different directions and is scattered across the sky by the gases and particles present in the atmosphere. This scattering of sunlight in the atmosphere is called Rayleigh scattering. When sunlight falls on water, the longer wavelength lights like red etc. are absorbed by the water. The blue wavelength light is absorbed least by the ocean water and is scattered and reflected back to the eyes.... Hence, Option (C) is correct. ... Hope it helps. Regards.
