Answer:
The correct answer is letter "C": normative principles tell us how people should behave, and positive principles tell us how people will behave.
Step-by-step explanation:
The discrepancy between the normative and positive statements in economics is substantially big. Economists use both types of statements when addressing economic issues with varying degrees of objectivity. Normative economics involves premises related to subjectivity and purpose. Positive economics, on the other hand, states facts and gives no sign of acceptance or disapproval.
