Answer 1

The correct statement regarding how the Seven Weeks’ War (also known as the Austro-Prussian War) affected German unification is: It allowed Prussia to unite with the northern German states.

The war took place in 1866 and resulted in a decisive Prussian victory over Austria. Following this victory, Prussia established the North German Confederation, which included many of the northern German states. This was a significant step towards the unification of Germany under Prussian leadership, ultimately leading to the proclamation of the German Empire in 1871.
