germany
the soviets
czech kings

The correct answer is A. Hungary.

Explanation

From the eleventh century, the Slovaks settled in the north of the kingdom of Hungary, leading a peaceful relationship with the Hungarian people until the nineteenth century despite the Ottoman invasions. However, the relationship deteriorated when the Slovaks supported by the Habsburg emperors showed their position against the Hungarian government causing the intensified persecution against Slovakians during the period of the Austro-Hungarian Empire (1867 - 1918). Later, with the creation of Czechoslovakia in 1918, the Slovak region was annexed to this country in conjunction with Bohemia and Moravia. So, the correct answer is A. Hungary
