The answer is B. The legal process in which a court order takes away a person’s citizenship is called denaturalization.  

Natural born citizens may not be deprived of their citizenship in the United States, since it is a birthright guaranteed in the 14th Amendment. Nonetheless, it is possible for a naturalized citizen to be subject of denaturalization; the process occurs in federal court and on specific grounds related also with the rules of federal civic court cases.
