Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
When white light falls on the compact disc, the light gets split into multiple colours. The CD acts as a prism here. Due to different refractive indices for different colours. Thus they get refracted at different angles and multiple colours are visible.
Therefore, both Assertion and Reason are correct and the Reason is the correct explanation for assertion.
