Opinion tells an uncertain statement that may be valid or not while a fact is a statement that is tested to be true based on facts. In this case, the opinion statement is C since the event will still take place that is next year which puts uncertainty element to the statement given. The answer then is C.
Ok, well, since it looks like you need a descriptive answer, here it is:
Hitler was in Berlin, Germany when the Russians stormed the city. He was barricaded in a bunker and all people sent out of the bunker were killed. So Hitler, seeing not much choice he decided to kill himself. So in April of 19945, he shot himself and supposedly took a dose of cyanide. His Mistress who he just married was also supposedly shot but people to this day debate whether she died by poison or by a gunshot by him and burned. There are many conspiracies out there but for the sake of you assignment, he is believed to have shot himself and his mistress/wife .
I need more context to be able to answer this. Feel free to dm it to me
