Question

An international treaty known as Montreal Protocol was signed to control emission of _______________.

• A. $UVrays$
• B. $Ozone$
• C. $CFC$
• D. $Oxygen$

Answer 1

The correct option is B $Ozone$

The Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. Montreal Protocol is a landmark agreement that has successfully reduced global production, consumption, and emissions of ozone-depleting substances (ODSs). ODSs are also greenhouse gases that contribute to the radiative forcing of climate change.

So, the correct answer is 'Ozone'.
