The correct option is C (a), (b), (c) and (d)
“Greenhouse effect is the process by which radiations from the sun are absorbed by the greenhouse gases and not reflected back into space. This insulates the surface of the earth and prevents it from freezing.”
Greenhouse gases are the gases that absorb the infrared radiations and create a greenhouse effect. For eg., carbondioxide and chlorofluorocarbons.”
Carbon dioxide, water vapours, chlorofloro carbon and ozone gas are green hours gases.
Hence, (c) is the correct option.
