In the seventeenth century, the Hapsburg Empire OA) lost control of Hungary, Croatia, and Slavonia to the Turks.
O B) retained its Holy Roman Empire in Germany.
C) remained a collection of territories.
D) established a centralized, absolutist state.

I believe the answer is C: Remained a collection of territories.

Explanation: Before the 17th century the Hapsburg Empire spent its time vastly expanding their territory, but by the end of the 16th century, they reached the zenith of their power, and I THINK that after/towards the end of the 17th century, they began to fall.

I hope this helps~!
