The ozone layer over the Arctic change with the seasons as "it peaks in spring and decreases in fall".
<u>Option: B</u>
<u>Explanation:</u>
The variations with the seasons in ozone layer over the Arctic is triggered by Polar Stratospheric Clouds (PSCs) developing in the polar regions during winter. These clouds have a surface area where the chemical reaction of CFC occurs at a rapid rate that induces ozone depletion in the polar stratosphere by as much as 50%. It occurs in the spring, as the temperature begins to warm up, resulting in an rise in the chemical reaction rate of these cloud surfaces.
