C. Stir the solution

There's 3 main factors you should know that affect dissolution:

Temperature : The $color(blue)("higher")$ the temperature, the $color(blue)("more")$ solute you will dissolve.
Agitation: The $color(blue)("more agitated")$ the solution, the $color(blue)("more")$ solute you will dissolve.
Particle Size: The $color(red)("larger")$ the particle size, the $color(red)("less")$ solute you will dissolve.

Given this:

Answer A is incorrect: Decreasing temperature will only decrease the amount of solute you dissolve.

Answer B is incorrect: Allowing the solution to settle means that you are not agitating it, which means you will not dissolve as much solute.

Answer D is incorrect: Larger particles mean that you will dissolve less solute.

Answer C is correct: By stirring, you're agitating the solution, which means you'll dissolve a greater amount of solute.

Hope that helped :)
