Final answer:
Travis Hirschi's control theory suggests that deviance is more likely among people with weak social bonds, hence youngsters with no engagement in social activities are most at risk.
Step-by-step explanation:
According to Travis Hirschi's control theory, deviance arises when an individual's bonds to society are weakened or absent. The category of people most likely to engage in deviance are those who lack strong social bonds that are formed through attachment, commitment, participation in conventional activities, and shared beliefs. Therefore, from the provided options, the category most likely to engage in deviance would be youngsters who "hang out" waiting for something to happen, as this suggests a lack of engagement in socially constructive activities, which can weaken social bonds and increase the temptation towards deviant behavior.
