Answer:
D.
Step-by-step explanation:
The second amendment states that every person has the right to own guns for safety reasons and for personal protection. To maintain a militia is just another part of the second amendment that you can create a military group as long as it is well regulated. If it is not A, then try D next. Hope this helps! James Madison proposed the second amendment after the constitution was ratified to provide more power towards state militas. "A well regulated militia being necessary to the free state."
