There is a woman who just passed away and was asked to choose one between two available doors. One door is a door to heaven, and another one is a door to hell. Each door has one guard. The guard of heaven always tell truth, and the guard of hell always tell lies.

What the question should be, and which door should be chosen if heaven is her goal?
