Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The particles in the atmosphere are responsible for the scattering of light. Since blue has the least wavelength, it is scattered the most and the sky appears blue.
In the absence of atmosphere, no scattering will occur and the sky will appear black.
Therefore, both assertion and reason are correct, and the reason is the correct explanation of assertion.
