Final answer:
Among the provided options, the captain of the football team is least likely to be targeted for bullying due to their higher social status and peer regard, which serve as protective factors.
Step-by-step explanation:
In considering which adolescent is least likely to be targeted for bullying, it's important to understand the dynamics of bullying behavior in the social context of adolescents. Those with perceived differences or who do not conform to societal norms, such as a child with a physical disability, a transgender adolescent, and an emotionally sensitive boy, are at a higher risk of being targeted for bullying due to such perceived vulnerabilities. In contrast, the captain of the football team is likely to have a high social status and be well-regarded by peers, which acts as a protective factor against being bullied. Therefore, the captain of the football team is least likely to be targeted for bullying among the options provided.
