Solution
The correct option is D
Neither 1 nor 2 Explanation:
Statement 1 is correct: The ice crystals provide a surface for a chemical reaction that changes chlorine in molecules that do not affect ozone (such as hydrogen chloride) into more active forms that do destroy ozone.
Statement 2 is correct: Nitrous oxide, like CFCs, is stable when emitted at ground level, but breaks down when it reaches the stratosphere to form other gases, called nitrogen oxides which trigger ozone-depleting reactions.
