The right answer is C Frederick II took Silesia.
The Austro-Prussian War had a rapid outcome and resulted in the Prussian victory over the Austrians. With this victory, the Prussians acquired much of the Germanic territories that had supported the Austrians during the war. And with the army of Frederick II in retreat after the unsuccessful assault on Bohemia, they found Silesia, where they obtained three decisive victories and resulted in the Treaty of Dresden in 1745. In half a century, Prussia tripled its population due to the acquisition of Silesia through this treaty.
In addition, this new scenario made it possible for Austria to be excluded from participating in any matter debated by the German Confederation. The Austrians were also obliged to pay a war indemnity to the Prussians.
