    The right choice is "HNO₃ + KOH → KNO₃ + H₂O "

    Explanation:

    acid-base neutralization reaction is a reaction in which acid react with base to form salt and water.

    Sn + 2HF → SnF₂ + H₂

    This is a reaction between metal (Sn) and acid (HF)

    2. C₂H₄ + 3 O₂ → 2 CO₂ + H₂O

    This is a combustion reaction

    3. MgCl₂ + Ca (OH) ₂ → Mg (OH) ₂ + CaCl₂

    This is a simple displacement reaction between salt (MgCl₂) and base (Ca (OH) ₂).

    3. HNO₃ + KOH → KNO₃ + H₂O

    This is a acid-base neutralization reaction in which acid (HNO₃) react with base (KOH) to form salt (KNO₃) and water (H₂O).

    So, the right choice is "HNO₃ + KOH → KNO₃ + H₂O"
