Correct option is B
As
turbidity increases in water, the scattering of light changes, causing a shift in the radiance peak towards longer wavelengths in the visible spectrum. This shift is towards the
red part of the spectrum, which is why muddy or highly turbid water often appears
brown or reddish. The presence of suspended particles in the water leads to greater scattering of shorter wavelengths (blue and green) and enhances the visibility of longer wavelengths (red).
