The given reaction is a double replacement reaction; option B.
<h3>What is a chemical reaction?</h3>
A chemical reaction is a reaction in which chemical changes occurs in the atoms of reactants which results in the formation pf products.
The given reaction is as follows:
- Ionic compound + Ionic compound ---> Ionic compound + Ionic compound
Since exchange of ions occur, it is a double replacement reaction.

Answer: Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of 
solution = 0.338 M
= volume of solution = 25.7 ml
= molarity of 
solution = 0.155 M
= volume of solution = ?
= valency of = 1
= valency of = 1
Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
