B) Increase

Explanation : When you add pure water to an acidic solution, the solution becomes less acidic and the pH goes up -- to a point. For example, if you add pure water to a relatively acidic solution that has a pH of 3.5, the pH level might go up to a 4 or 5. You cannot, though, turn an acidic solution into a base solution or make it neutral just by adding water. As a result, pure water can only raise the pH of an acidic solution to a maximum of a 6.9.
