Which countries comprised the Central Powers during World War I?

The Central Powers during World War I were primarily composed of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. This coalition formed in opposition to the Allied Powers, which included nations like France, Britain, and Russia.

Germany was a dominant force within the Central Powers, militarily and industrially, driving much of the aggression and strategies during the war. Austria-Hungary, whose conflict with Serbia triggered the war, relied heavily on Germany for support. The Ottoman Empire joined the alliance seeking to regain territory and maintain power amid its declining status. Bulgaria, entering the war later, aligned with the Central Powers primarily to recover territories lost in previous conflicts, particularly against Serbia and Greece.

The other groups listed in the choices belong to the Allied Powers or were neutral nations during World War I. Therefore, the grouping of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria accurately reflects the composition of the Central Powers in this global conflict.
