The correct option is B warming effect

'Greenhouse effect' refers to a process of warming of earth due to the absorption of radiation emitted by earth by greenhouse gases like carbon dioxide, water vapour etc in the atmosphere. It has become a major problem now as the concentration of greenhouse gases is increasing due to pollution and this is resulting in increased temperature of earth which is dangerous as it can lead to melting of ice on earth's surface and rise in sea levels.
