Answer:

A option

Explanation:

Because recatants are in solid form having less enetropy and products are liquid form having more entropy

While other options reactants and products are in same phase gas phase having same entropy

The reaction that would result in increased entropy is the combustion reaction;

KNO3(s)--->K+(aq)+NO3-(aq). Option A

This is further explained below

What is a combustion reaction?

Generally, a combustion reaction is simply a combustion process that occurs when a material combines with oxygen gas, producing energy as light and heat.

In conclusion, the chemical reaction KNO3(s)--->K+(aq)+NO3-(aq) is has all properties of a combustion reaction as the solid reactants gives an aq solution.
