The best answer is "was not part of the Eastern Bloc",
although this answer is misleading.
Yugoslavia was indeed part of the Eastern Bloc in the sense that it was an Eastern European communist country, but it was the only one that did not align itself with the USSR after 1948. It also did no ally with the United States, choosing non-alignment instead.
This answer is the best answer simply because it is less false than the other answers, which are completely wrong. Yugoslavia never joined the USSR, choosing to split from Stalin in 1948, and never became a satellite nation of the US, and isn't located anywhere near the Baltic.

Explanation: Imperialism was about almost everywhere in Europe at the time and around that time most European countries had territories in Africa which lead to constant fighting for the land there. What this lead to was intense fights between nations by them creating proxy wars (militias/Rebel groups) to fight against each other which were being supplied by that country that wants more land for them self. With that it lead to Archduke assassination which lead countries to declare wars on one country which then would mean they would declare war on multiple countries in realty because countries would ally each other and the domino effect went down hill from that. So Archduke assassination was just really a "reason" to fight with another nation for more land (resources).
