Which of the following represents a neutralization reaction which hydrofluoric acid and sodium hydroxide(a base) react to produce sodium choride(a salt) and water? 

Explanation:

A neutralization reaction is a reaction that involves an acid and a base.

When an acid reacts with a base to produce salt and water only, the reaction is said to be a neutralization reaction.

  Acid    +  Base    →  Salt  +  Water

Such reactions are classified as a double displacement reaction in which a non-ionizing product is formed
