Solution

The correct option is A $K O_{2}$
Potassium peroxide ( $K O_{2}$ ) is often used in self-contained breathing devices, such as those used in fire emergencies, because it reacts with exhaled $C O_{2}$ to form $K_{2} C O_{3}$ and $O_{2}$

$4 K O_{2} + 2 C O_{2} \to 2 K_{2} C O_{3} + 3 O_{2}$

Hence option $A$ is correct.
