Answer: i believe the answer B Kosovo
Explanation: the population of Kosovo belongs to the ethnic Albanians, of Islamic religion and antecedents in the Ottoman invasions to Europe, while the Serbian, Slavic, and Christian population makes up the remaining 10%.
That situation has been historically conflictive and has reached peaks of violence as in the Yugoslav Wars. That is why, since the Kosovars formed their own government in 2008, the Serbian population began to withdraw from the territory.
