which statement best describes the process of making a solution by diluting a stock solution? add more…

Brief Explanations:

Dilution involves increasing the amount of solvent. When more solvent is added to a stock - solution, the amount of solute remains the same while the total volume of the solution increases. According to the concentration formula $C=\frac{n}{V}$ (where $C$ is concentration, $n$ is the amount of solute, and $V$ is the volume of the solution), as $V$ increases with a constant $n$, the concentration $C$ decreases.

Answer:

Add more solvent to decrease the concentration.
