Explanation:

The Congress of Vienna (1815) was convened after Napoleon's defeat to restore order in Europe. Its core goal was to reestablish political balance and prevent future conflicts, making the return of peace and stability the primary aim. Other options are incorrect: Napoleon was already defeated before the congress; Vienna was not made a commerce center; Metternich was a key negotiator, not a replacement for Napoleon.

Answer:

that peace and stability would return to war-torn Europe.
