Solution

The correct option is C CFCs
The presence of CFCs in the atmosphere results in the depletion of the ozone layer in the stratopshere. CFCs are used as coolants in refrigerators, coolers, etc. The CFCs causes breaking of the ozone molecule which forms the oxygen radical and O2. The depletion of the ozone layer leads to the formation of ozone hole which causes the penetration of the harmful UV radiations from the sun into the Earth's atmosphere.
Thus, the correct answer is option C.
