Read the following statements regarding the breakdown of the ozone layer:
Statement I: UV radiation acts upon Chlorofluorocarbons (CFCs) in the stratosphere to release active Chloride radicals.
Statement II: A single Chlorine radical is consumed after destroying one Ozone molecule and cannot participate in further reactions.
Which of the options is correct?

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The thickness of the ozone layer is measured in Dobson Units (DU).
Reason (R): The ozone layer is found in the Troposphere and protects us from harmful UV-B radiation.
