What role does stirring play in increasing the rate of a solid dissolving in a liquid?

• Stirring reduces the amount of solute that dissolves.
  

• Stirring keeps the solute particles in suspension, increasing contact with the solvent.
  

• Stirring slows the dissolving process by breaking up the solute particles.
  

• Stirring has no effect on the dissolving process.
