Explanation

The historical accounts indicate that Prophet Muhammad (PBUH) passed away at his home in Medina, not specifically in the cottage of any of these women. Option A is incorrect because Hazrat Khadija (RA) passed away before this time. Option B is incorrect because while she was present, the primary location associated with his passing is his own residence. Option C is incorrect because although she was close to him, the specific location mentioned in historical texts points elsewhere or generally to his home.
