the sky apperars blue because light is scatterd and blue light which is of shorter wavelength will be in the sky where in most of longer wavelength rays red ones travel straight.. so the sky is blue in colour

Our atmoshere is made of dust and gas molecules. As light enters the atmoshere, which gets thicker as you get closer to the ground, it bumps into a gas molecule, for example. The light is absorbed by the molecule until the molecule radiates this same light ( wavelength) but in a different directions. Most of the reds, for example, are not effected and can travel straight through without being effected. However, the shorter wavelengths, the blues, are absorbed by the molecules and then are radiated off in all directions. So no matter where you look the blue light is reflected in that direction.
So I'd have to say it is 'C'

I'm not sure any of those answers is most technically accurate but B is definitely wrong. If it scattered blue light effectively it would not appear blue. The answer may be D but the problem with D is that if you scatter all the red light from full spectrum light you will not be left with blue light, there are other colors in there.

The page listed as source seems to agree with me. The specific composition of our atmosphere scatters all wavelengths of visible light BUT blue more effectively.

I do know that the sky is not actually blue, but I cannot tell you the reason. B makes sense though.

I thought It had something to do with the planets
water ( seas and oceans ) being blue, and It
reflects It's blueness In the sky.

If so I guess that would mean ( b ) . :-)
