carbonic anhydrase inhibition

Considering the bicarbonate buffering system in the blood, if the enzyme carbonic anhydrase's activity is inhibited, wouldn't this lead to an increased concentration of CO2 AND H2O at the tissue level? I'm reviewing the AAMC Sample Exam and I selected that CO2 concentrations would increase (correct answer), but now that I'm thinking about it... wouldn't H2O concentrations increase (also an answer choice, albeit incorrect) as well?

Many thanks

Edit- For reference: question 48 on AAMC...
