To determine which solution will have the greatest number of \( \text{H}_3\text{O}^+ \) ions at equilibrium, we should consider the characteristics of the solutes given:
1. **Strong Acid**: Fully dissociates in water, producing a high concentration of \( \text{H}_3\text{O}^+ \) ions.
2. **Weak Acid**: Partially dissociates in water, resulting in a lower concentration of \( \text{H}_3\text{O}^+ \) ions compared to a strong acid of the same initial concentration.
3. **Strong Base**: Fully dissociates to produce \( \text{OH}^- \) ions but doesn't produce \( \text{H}_3\text{O}^+ \) ions directly. The equilibrium will shift to consume \( \text{H}_3\text{O}^+ \) ions, thereby decreasing their concentration.
4. **Weak Base**: Partially dissociates to produce \( \text{OH}^- \) ions, which can also reduce \( \text{H}_3\text{O}^+ \) concentration through equilibrium shifts.
Given this information, the solution that will produce the greatest number of \( \text{H}_3\text{O}^+ \) ions at equilibrium is the **strong acid**. Strong acids completely dissociate to give a high concentration of \( \text{H}_3\text{O}^+ \), significantly more than weak acids, weak bases, or strong bases.
So, the correct answer is: **strong acid**.
