In terms of Kohlberg's theory, Frank is at the conventional level of moral reasoning.

Explanation:

Lawrence Kohlberg used stories with moral dilemmas in his research to develop his theory of moral development. According to him, there are three possible stages: pre-conventional, conventional, and post-conventional.

Children are found to be at the first, the pre-conventional stage of morality. Most teenagers and adults can be placed in the second one, as is the case with Frank. People at the conventional stage internalize the rules or values of adult role models. They basically accept norms as they are, without questioning or trying to see and develop them for themselves. Authority, at this stage, is not questioned. Finally, those who reach the third stage, post-conventional, are capable of coming up with their own sense of moral values and ethical principles, questioning authority and the imposition of rules.
