Final answer:
Questions about duty delve into two categories: the pursuit of good things and the adaptability of life teachings regarding moral obligations. Hence, option (B) is correct.
Step-by-step explanation:
The question posed concerns the nature of duty and suggests that there are two categories to consider. Firstly, there is the duty that relates to the pursuit of good things, implying that our moral obligations might be tied to the outcomes that promote well-being or virtue.
Secondly, the question implies that duty is not static; it is informed by life teachings that can change over time, suggesting a certain flexibility or adaptability of moral norms as they apply to different circumstances.
About philosophical theories, we can consider the Divine Command Theory, which holds that an action's moral status is determined solely by God's will. Kant's Categorical Imperative offers an alternative perspective, where the goodness of an action is determined by the intention and the universalizability of the action, rather than its outcome.
Additionally, the complexity of real-life situations can lead to uncertainties in moral decision-making, acknowledging the challenges of discerning our actual duty. These cultural and philosophical perspectives suggest that duty is not one-dimensional and that moral life is an ongoing practice of aligning our actions with a changing understanding of duty.
