What is the ruling on expiation for someone who suffered a stroke before Ramadan, and at the beginning of her illness was partially losing consciousness, then entered into a full coma before Ramadan and passed away during it, with doctors stating that she could hear?

This woman, who suffered a stroke before Ramadan and remained unconscious, feeds a poor person for each day, because unconsciousness does not negate the obligation to fast, whereas it does negate the obligation to pray if it was not by her choice. However, if the unconsciousness was by her choice, such as due to anesthesia, then she is required to make up (the prayers).
