Assertion `:` The setting sun apears to be red.
Reason `:` Scattering of light is directly proportional to the wavelength .

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false.

`I prop (1)/(lambda^(4))`
