The correct answer is: c) Opponents of the war refused to register, burned their draft cards, moved or made up health conditions.
In 1964, as the military draft was reinstated during the Vietnam War, many young men opposed to the war took various actions to resist the draft, including refusing to register, burning their draft cards, relocating to avoid service, or seeking ways to obtain deferments by claiming health issues. The anti-war movement was growing at this time, and resistance to the draft became a significant aspect of that movement.
