Why does stirring increase the rate of dissolution?

AStirring the solution decreases the kinetic energy of the solution.
BStirring the solution increases the surface area of the solution.
CStirring the solution decreases the agitation of the solution.
DStirring the solution increases the contract between solute and solvent.
EStirring the solution decreases the temperature of the solution.

The only option that makes sense is D). Stirring will increase the contact between solute and solvent.

The correct option is D.

When dissolving a substance in a solvent, stirring the solution will increased the rate at which the substance dissolved. This is because, when one stirs a solution, it exposes more surface area of the solute to the solvent, thus, increasing the interaction between the solute and the solvent. The higher the quantity of the solute that is exposed to the solvent, the higher the rate of dissolution of the solute.
