what is your opportunity cost, what economic resources are needed, why should these resources be used?

Explanation:

In economics, the three fundamental economic questions that all economic systems (traditional, command, market, mixed) must answer are "What to produce" (determining the goods/services), "How to produce" (the production methods), and "For whom to produce" (distributing the output). The first option matches these three core questions. The other options include non - fundamental or incorrect questions (like "why to produce", "when to produce", or questions about opportunity cost and resource needs which are not the three basic economic questions for comparing economic systems).

Answer:

A. What to produce, how to produce, and for whom to produce?
