Solution

The correct option is C PCl5 is decreased
When CO is added to the above system, the second reaction will go backwards in accordance with Le Chatelier's principle and hence, the concentration of the common molecule, i.e., Cl2 will also reduce.
So, to counteract the decreased concentration of chlorine, first equilibrium will go forward and hence, the concentration of PCl5 will decreased.
