In the equilibrium represented by the equation:

\[ B + H_2O \rightleftharpoons BH^+ + OH^- \]

when the strength of the base \( B \) in a solution is increased, more \( B \) will react with water to form \( BH^+ \) and \( OH^- \). This increase in base concentration will drive the reaction to the right, according to Le Chatelier's principle.

As a result, the number of \( BH^+ \) ions will increase, and the number of \( OH^- \) ions will also increase, while the amount of water (\( H_2O \)) will remain relatively unchanged because it is the solvent.

Therefore, the correct response from the provided options is:

**The number of BH\(^+\) molecules will increase, and the number of OH\(^-\) ions will increase.**

However, since this specific option is not listed accurately in your responses, the most relevant description would be:

**The number of BH\(^+\) molecules will increase, and the number of water molecules will decrease.**

But note, normally the water quantity doesn't significantly decrease as it acts primarily as a solvent. The implication is that the concentration of \( BH^+ \) and \( OH^- \) increases, which reflects an increased base strength.

If you're seeking an option that was provided accurately concerning the increase in \( OH^-\), consider:

**The number of OH\(^-\) ions will increase, and the number of BH\(^+\) molecules will increase.**

Just clarify that the water does not significantly decrease.
