Explanation:

After Napoleon's defeat, the Congress of Vienna aimed to restore the pre - revolutionary order. This led to the restoration of many monarchies across Europe. The French Revolution spreading to other countries was during Napoleon's rise, not after his defeat. France was not reduced to half its size, and Britain and Prussia became more powerful, not less, after Napoleon's defeat.

Answer:

D. Many monarchies were restored.
