The correct answer is C. The primary purpose of state militias was to protect from attacks by Native Americans.
Explanation:
The state militias were created prior to the sanction of the Constitution in 1787, as a means of defense of each state outside the armed forces controlled by the federal government. Its main objective was to provide for the defense of the territory of each state, while the federal army did the same at the borders of the nation. As the states were in peaceful coexistence under the Articles of Confederation, the main threat that the militias faced were the attacks of Native Americans.
