Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Image forms with large number of rays and painting middle portion would block few rays only, so complete image will form but the intensity would be low because intensity depends on number of rays refracted or reflected, here few rays get blocked by black paint so intensity decreases.
