Answer:
D the draft
Step-by-step explanation:
Conscription, sometimes called the draft, is the mandatory enlistment of people in a national service, most often a military service.
The draft is officially known as the Selective Service. ... Basically, this means that if we ever have a national emergency or war that the all-volunteer military cannot adequately support, Congress and the president can reinstate the draft and force male citizens to serve in the military.
