Final answer:
Deontological ethics reflects the approach of a principle-based ethical tradition by emphasizing the adherence to moral rules and duties.
Step-by-step explanation:
The question asks which statement reflects the approach of a principle-based ethical tradition. The answer is option 2) Deontological ethics emphasizes following moral rules and duties.
This is because deontological ethics, which emphasizes duties or rules to determine the rightness of an action, centers around principles stating that actions are right when they conform to the correct rule or duty, regardless of the consequences. This tradition, largely influenced by philosophers like Immanuel Kant, suggests that certain actions are inherently right or wrong, and that individuals should adhere to these moral duties.
