Answer:
D). Congress has created specialized courts to deal with such cases.
Step-by-step explanation:
The federal district courts were established by the United States' Congress subject to the 'Judiciary Act of 1789' to primarily deal with the criminal as well as civil cases. These courts do not interfere in the cases associated with the military law, grievances in opposition to the government, or disputes associated with the taxation as these matters are different from the civil affairs. Thus, 'congress has created 'specialized courts' to handle these cases' as military matters must be solved in reference to the military law which is difficult for civil courts to deal with. Similarly, the other disputes against taxation policy or government has special legal provisions that requires special concern. Hence, option D is the correct answer.
