Solution

The correct option is A $10 m l, 5 m l$
$C H_{4} + 2 O_{2} \to C O_{2} + 2 H_{2} O$

One mole of methane will require 2 moles of oxygen to produce one mole of carbon dioxide.

22.4 L of methane will require 44.8 L of oxygen to produce 22.4 L of carbon dioxide.

Hence, 5 ml of methane will require 10 ml of oxygen to produce 5 ml of carbon dioxide.
