The correct answer is C) military.
The type of law that this statement illustrates is military law.
In legal terms, when we refer to military law we are talking about the body of law that enforces loyalty and discipline in the United States Armed Forces, which are the Army, Navy, Air Force, and Coastal Guard.
There is another term that means something similar in the Armed Forces and is martial law. However, it is not used frequently because can be confused with military rule during a crisis.
The military and its members are very strict in the enforcement of the military law and do not allow civil courts to intervene in military cases.
