The correct answer is option C
You do not bury the survivors of a plane crash!
The question asked where the survivors would be buried, survivors of a plane crash are not buried as they are still alive, and they are usually rushed to the hospital for immediate medical treatment for possible injuries that may be incurred during the crash.
Only the dead are buried, the dead can be buried in Germany, Poland or Switzerland, I believe this is up to the family of the deceased to determine where they will be buried. This makes options A, B,D, and E wrong.
Hope this helps.
