Answer:

The stock solution

Explanation:

When preparing a series of solutions from a stock solution, the stock solution will always be the most concentrated solution of the set. Each of the subsequent solutions are prepared by dilution, which entails adding solvent to a portion of the stock solution. This will always result in a solution that is less concentrated than the stock solution.
