He used Prussia’s powerful army to defeat Austria and France and unify the German states.

Answer 1

Otto Von Bismarck played a crucial role in the unification of Germany primarily through his strategic use of Prussia's military power and cunning diplomacy. The correct statement regarding his contribution to the unification of Germany is:

He used Prussia’s powerful army to defeat Austria and France and unify the German states.

Bismarck orchestrated the Austro-Prussian War in 1866, which resulted in a decisive Prussian victory and led to the exclusion of Austria from German affairs. He then went on to provoke the Franco-Prussian War of 1870-1871, which united the various German states against a common enemy, fostering a sense of nationalism. The successful conclusion of this war further solidified the unification process, culminating in the proclamation of the German Empire in 1871, with Wilhelm I as its emperor.
