The correct option is 2 only
Explanation
Opportunity cost is a fundamental economic principle arising from the scarcity of resources (factors of production). It represents the potential benefits an individual, investor, or society misses out on when choosing one alternative over another.
Statement-wise Analysis:
- Statement 1 is Incorrect: Opportunity cost is formally defined as the value of the next best alternative forgone. It quantifies the trade-off involved in any decision where resources are limited.
- Statement 2 is Correct: Resources (land, labor, capital) are scarce. If resources are diverted to produce corn, they are withdrawn from the production of other goods, such as cotton. Consequently, the production of cotton will decrease, not remain unaffected. This trade-off is often illustrated by the Production Possibility Frontier (PPF).
- Statement 3 is Incorrect: The concept applies to all economic agents, including individuals, firms, and society as a whole. Societies must make choices on how to allocate limited resources (e.g., spending on defense versus healthcare), making the concept highly relevant at the macroeconomic level.
Key Takeaway:
Opportunity cost is the cost of the next best alternative sacrificed to pursue a certain action; it dictates that because resources are scarce, every economic choice involves a trade-off.
