Final answer:
The law establishes an agent's legal duties, which include responsibilities that are mandated by law, such as serving as a juror or in the Armed Forces. These differ from moral and ethical duties, which are based on moral principles and societal expectations. Option C is correct.
Step-by-step explanation:
The law establishes an agent's legal duties. Legal duties are those responsibilities that are required by law. For instance, serving as a juror or serving in the Armed Forces are mandated by law. These responsibilities can be contrasted with moral duties, which may not be legally enforced but are considered good behaviors that citizens should practice based on ethical considerations.
In the philosophical concept known as the social contract, individuals accept certain moral and political obligations as part of society. Additionally, agents may have ethical duties which align with moral principles and norms of professional conduct. Therefore, the best answer to the question is C. Legal.
