The gases that produce green house effect are

Options

  2. BCO2, N2O,H2\mathrm{CO}_2, \mathrm{~N}_2 \mathrm{O}, \mathrm{H}_2
  3. CCFCs,NO2,O2\mathrm{CFCs}, \mathrm{NO}_2, \mathrm{O}_2
  4. DCO2, N2\mathrm{CO}_2, \mathrm{~N}_2, water vapour

Correct answer

A. CH4,(CFCs),CO2\mathrm{CH}_4, \mathrm{(CFCs)}, \mathrm{CO}_2

Step-by-step solution

Green house effect is the CO2\mathrm{CO}_2 effect. It is due to CO2\mathrm{CO}_2 layer in atmosphere and also by (CFCs),SO2,NO2,CH4\mathrm{(CFCs)}, \mathrm{SO}_2, \mathrm{NO}_2, \mathrm{CH}_4. These gases come from factories, automobile, agriculture, refrigerators, deforestation. These gases entrap the solar heat and prevents the escape of heat from earth to outer space, thus increasing the temperature of earth which further lead to global warming.
