Final answer:
The college student who follows peer pressure and drinks because others do it exemplifies Conventional morality, the second stage in Kohlberg's moral development theory.
Step-by-step explanation:
The college student who drinks because "everybody else is doing it" is at the second stage, or Conventional morality (B), of moral development. This stage is characterized by an individual's acceptance of society's conventions concerning right and wrong. At this level of Kohlberg's theory of moral development, individuals act with the expectation of fulfilling social roles and expectations. As they mature through their teen years, individuals become increasingly aware of others' feelings and take them into consideration when determining their moral stance, following rules and laws to maintain social order and secure approval from others.
