(c) absorbers
(d) none of the above

Reason — Green house effect is the process of warming of the earth’s surface and it’s lower atmosphere, by absorption of infrared radiations of long wavelength emitted out from the surface of the earth by greenhouse gases such as carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbon (CFCs), etc.
