Correct answer: (a) presence of gases, which in general are strong infrared absorbers, in the atmosphere
Explanation:
Green house gases such as CO2, 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.
