Solution

The correct option is B hydrogen ion concentration will decrease
If $C O_{2}$ escapes from the given system, then according to Le Chatelier's principle, the backward reaction will start and due to this backward reaction the concentration of $H^{+}$ ions will be decreased leading to increase in pH.
