There's a thing...
They wouldn't ever let you do that unless the patient has moved, deceased or have changed doctor's , If you could get a chance to do that and they caught you , the patient would give you a notice or incase the doctor sended something to her/him and someone else would get the mail , and it could be very important ..hoped this helped
I would go for B. Production of immune cells
