asset class Prescription {…}

interface Pharmacy {
  void depositPrescription(Prescription @ Owned >> Unowned p);  
  Prescription @ Owned removePrescription(Prescription @ Unowned p);
  Prescription @ Unowned getAnyPrescription();
}
 
class Patient {
  void fillPrescription(Pharmacy @ Unowned pharmacy, Prescription @ Unowned pre) {
    pharmacy.depositPrescription(pre); // Location (A)    
    
    Prescription pre2 = pharmacy.getAnyPrescription(); [pre2 @ Unowned];
    Prescription removedPrescription = pharmacy.removePrescription(pre2); [removedPrescription @ Owned]; // Location (B)
    pharmacy.depositPrescription(removedPrescription); [removedPrescription @ Unowned]; // Location (C)
    // Location (D)
  }
}

At Location (D), what ownership does removedPrescription have according to the compiler?
