Answer:
The correct answer is D. Europe established a balance of power following the Napoleonic Wars.
Explanation:
The Congress of Vienna took place between November 1814 and June 1815 in the backdrop of the disastrous Napoleonic wars that had left much of continental Europe in disarray.
After the defeat of Napoleon Bonaparte, delegates from the four great powers of Europe, Great Britain, France, Russia and Austria met in Vienna to discuss ways of limiting further conflict.
