According to the chemical equation,

CH4 (g) + 2O2 (g) → CO2(g) + 2H2O (g)

44g CO2 (g) is obtained from 16 g CH4 (g).

Number of moles of CO2 (g)=0.5 mol

Hence, 0.5 mol CO2 (g) would be obtained from 0.5 mol CH4 (g)

or

0.5 mol of CH4 (g) would be required to produce 22 g CO2(g).

Therefore the correct option is (3).
