Solution

The correct option is A $C O$
When potassium ferrocyanide is heated with concentrated sulphuric acid, $C O$ gas evolves through a non redox reaction.
The reaction is,
$K_{4} [F e (C N)_{6}] + H_{2} S O_{4} \to 4 K H S O_{4} + H_{4} F e (C N)_{6}$
On heating , $C O$ gas is evolved at slow rate.
