Solution
The correct option is C substances that deplete the ozone layer
Montreal Protocol is an international treaty that was signed at Montreal, Canada in the year 1987.
It was designed to protect the ozone layer present in the stratosphere (atmospheric layer) by phasing out the production of numerous substances that deplete ozone.
Ozone protects the Earth from the harmful UV radiations from the sun. Major pollutants responsible for the depletion of ozone layer are chlorofluorocarbons (CFCs), nitrogen oxides and hydrocarbons.
CFCs are widely used as coolants in air conditioners and refrigerators, cleaning solvents, aerosol propellants and in foam insulation. The threat to O3 is mainly from CFCs, which are known to deplete O3 by 14% at the current emission rate.
