A) presence of gases, which in general are strong infrared absorbers, in the atmosphere
B) presence of \[C{{O}_{2}}\]only in the atmosphere
C) pressure of \[{{O}_{3}}\] and \[C{{H}_{4}}\] in the atmosphere
D) \[{{N}_{2}}O\] and chlorofluorohydrocarbons in the atmosphere
Correct Answer: A
Solution :
Green-house gases such as. \[C{{O}_{2}}\], ozone, methane, the chlorofluorocarbon compounds and water vapour form a thick cover around the earth which prevents the IR rays emitted by the earth to escape. It gradually leads to increase in temperature of atmosphere.
