Answer & Solution
Option: B
Explanation :Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon. It is a colorless, faint ethereal, and sweetish-smelling liquid that boils around room temperature.
CFC-11 was phased out under the 1987 Montreal Protocol. Despite being the signatory to the Montreal Protocol, and agreeing to phase out production of CFC-11 in 2010, China continued to emit the polluting gas.
Between 40 and 60 per cent of total global CFC-11 emissions originate from Eastern China, reveals study. This is no good news for the ozone layer which is on the road to recovery.
