<u>D) Stirring up the solution</u> will obviously increases the speed of the solute the dissolving in water or any other liquids.
<h2>Explanation:</h2>
Stirring the solid solute in the water moves the solvent molecules around, making them interact with the hard chunks of solute that are yet to be dissolved and transport the solute which is dissolved into the bulk solution.
Stirring can dissolve a solid solute in a solvent, but it cannot control how much solute it can dissolve. Temperature affects how much solute can be dissolved in a solvent. When the solvent's temperature is high, it'll dissolve more solute.
