Answer:
b. masculinity hypothesis
Step-by-step explanation:
The masculinity hypothesis was developed by Messerschmidt to explain gendered bias in expressing masculinity through criminal behavior.
The idea is that when the person doesn't have stability in the masculine traits, like having a job, steady family, money success, they might be prone to violent behavior to express their toughness which is linked with gendered ideas of masculinity.
Women's gender norms tend to go a different way, so even when female delinquents fall out of their standard normative behavior, they would fall under this masculinity hypothesis.
