• D. avoid using any assumptions to ensure complete accuracy

Answer: (C)

Verified step by step guidance

1. Understand that economic models are simplifications of reality designed to highlight key relationships and mechanisms.
2. Recognize that including every possible real-world variable would make models too complex and less useful for analysis.
3. Know that relying solely on historical data without theoretical frameworks limits the ability to explain or predict economic behavior.
4. Acknowledge that making simplifying assumptions helps economists focus on the most important factors and relationships in their models.
5. Conclude that the correct approach is to make simplifying assumptions to create manageable and insightful economic models.
