Assertion In the absence of atmosphere the sky would appear black. Reason Atmosphere scatters the light and hence we get blue colour.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
Assertion: Without atmosphere, no scattering of sunlight occurs, so the sky appears black (as in space). Reason: The blue color of the sky is due to Rayleigh scattering of sunlight by the atmosphere. Thus, the absence of scattering explains why the sky would be black, so Reason correctly explains Assertion.
