Which of the following is an example of involuntary participation in a situation?

Involuntary participation refers to situations where an individual is compelled to engage in an activity without their consent or choice. Being trafficked for forced labor exemplifies this concept because the person is subjected to exploitation and cannot freely choose to participate in that situation. Their autonomy is completely disregarded, as they are coerced or manipulated into labor without the ability to leave or negotiate their circumstances.

In contrast, volunteering for community service, signing a contract for employment, and choosing a career path all involve voluntary participation. These scenarios are characterized by the individual's freedom to make choices and express consent regarding their involvement. Therefore, the correct answer highlights the stark difference between voluntary actions and situations of coercion where the individual lacks agency.
