**B.**
\[ 3KOH(aq) + H_3PO_4(aq) \rightarrow K_3PO_4(aq) + 3H_2O(l) \]
**C.**
\[ Na_2S(aq) + 2HCl(aq) \rightarrow 2NaCl(aq) + H_2S(g) \]
**D.**
\[ 2Na(s) + 2HCl(aq) \rightarrow 2NaCl(aq) + H_2(g) \]
**E.**
\[ Mg(s) + Cl_2(g) \rightarrow MgCl_2(s) \]

In this multiple-choice question, students are required to identify which reactions amongst the given options are classified as acid-base reactions. Each option provides a chemical equation that should be analyzed based on the concept of acid and base interactions.
**Explanation of Acid-Base Reactions:**
- **Acid-Base Reaction:** A reaction where an acid reacts with a base to produce salt and water.
**Analysis of the Given Choices:**
- **Option A:** This is not an acid-base reaction as it is a synthesis reaction where potassium forms a compound with phosphorus and oxygen.
- **Option B:** This is an acid-base reaction. Potassium hydroxide (KOH) is a base, and phosphoric acid (H₃PO₄) is an acid. They react to form potassium phosphate and water.
- **Option C:** This is not an acid-base reaction; this is a double displacement reaction where sodium sulfide reacts with hydrochloric acid to produce sodium chloride and hydrogen sulfide.
- **Option D:** This reaction involves a metal (sodium) reacting with an acid (HCl), which is more of a single displacement reaction where hydrogen gas is released.
- **Option E:** This is a combination reaction where magnesium reacts with chlorine gas to form magnesium chloride, not an acid-base reaction.
