(b) (A) is correct and (R) is incorrect.
(c) Both (A) and (R) are correct but (R) is not the correct explanation of (A).

Answer 1

Answer:

C is the correct answer

Explanation:

This is because sky appears blue in the morning and dark when moon shines but the dark sky has nothing to say as to why the sky appears blue

Answer 2

Blue light has shortest wavelength and highest energy.

Correct option is (C).

Explanation:

(C) both (A) and (R) are correct but (R) is not the correct reason of (A).

(A)- This is because molecules in the air scatter blue light in the sky from the sun instead of red.

Because the wavelength of blue light is shorter and scatters more than other lights.

Moreover blue light has shortest wavelength and highest energy.

Therefore the clear sky appear blue in day.
