Final answer:
The disanalogy that distinguishes the case of workers assuming a risk by choice from a case of coercion is that there may be other people willing to accept the job, suggesting that the worker had a choice in assuming the risk.
Step-by-step explanation:
The disanalogy that distinguishes the case of workers assuming a risk by choice from a case of coercion is option c: There may be other people willing to accept the job.
This disanalogy suggests that even if a worker faces risks in their current job, there may be other individuals who are willing to accept the same job willingly, implying that the worker had a choice in assuming the risk.
This contrasts with coercion, where a person is forced and does not have an alternative or choice.
