Question
Assertion :In free-radical chlorination reaction using UV−light,UV-light is required only for initiation reaction as Cl−Cl+UV→2Cl∗ Initiation Although free radicals are not consumed in overall propagation step and therefore, it appears that the reaction would continue to occur even in absence of UV source once initiated, continuous UV-bathing is required. Reason: Free radicals are consumed in termination step, therefore needs to be produced continuously.

Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
As the free radicals are consumed in termination step, therefore they need to be produced continuously. This is done by continuous UV bathing.
Hence, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
