HNO₃ (aq) + KOH (aq) → KNO₃ (aq) + H₂O(I)
The above reaction is an example of:

Correct option is B

The correct answer is (B) Neutralization reaction.

The given reaction is:

​$$\text{HNO}_3 \, (aq) + \text{KOH} \, (aq) \rightarrow \text{KNO}_3 \, (aq) + \text{H}_2\text{O} \, (l)$$​​

In this reaction:

• HNO₃ is nitric acid, and KOH is potassium hydroxide.
• The products are KNO₃ (potassium nitrate) and H₂O (water).
• This is a typical neutralization reaction, where an acid (HNO₃) reacts with a base (KOH) to produce a salt (KNO₃) and water (H₂O).
  

Information Booster:

• A redox reaction involves the transfer of electrons, but in this case, there is no electron transfer. Therefore, it is not a redox reaction.
  
• In a decomposition reaction, a single compound breaks down into simpler substances. This is not the case here.
  
• A combination reaction involves two or more substances combining to form a single product. Here, two reactants combine, but the result is not a single product, but salt and water.
