Answer: 4. Carbon dioxide and Methane

The main greenhouse gases are \(\mathrm{CO_2}\), \(\mathrm{CH_4}\), \(\mathrm{N_2O}\) and CFCs. Among the options, carbon dioxide and methane form the pair, so option 4 is correct.

Oxygen and nitrogen do not trap heat, and ozone, ammonia and \(\mathrm{SO_2}\) are not the main greenhouse gases.
