The HARDEST Logic Puzzle Ever (Simpler Version): Two Doors To Freedom Riddle

An evil warden holds you prisoner, but offers you a chance to escape. There are 3 doors A, B, and C. Two of the doors lead to freedom and the third door leads to lifetime imprisonment, but you do not which door is what type. You are allowed to point to a door and ask a single yes-no question to the warden. If you point to a door that leads to freedom, the warden does answer your question truthfully. But if you point to the door that leads to imprisonment, the warden answers your question randomly, either saying “yes” or “no” by chance. Can you think of a question and figure out a way to escape for sure?
