The practice of college deferments during the Vietnam War meant that most draftees who served in Vietnam came from the middle class.
Here's why:
1. College deferments allowed individuals enrolled in college to postpone their military service. This led to a situation where a significant number of individuals from the middle class, who had the means to attend college, were able to delay or avoid being drafted into the military.
2. In contrast, individuals from the working class, who may have been less likely to attend college due to financial constraints or other reasons, were not as eligible for college deferments. As a result, a higher proportion of draftees who ended up serving in Vietnam were from the middle class.
Therefore, the correct answer is:
A. middle class.
