Answer: Porter’s Five Forces is a framework for assessing industry structure that determines an industry’s long-run profitability

## Explanation **Option C is correct** because it accurately describes Porter's Five Forces framework: 1. **Porter's Five Forces** is indeed a framework developed by Michael Porter for analyzing the competitive structure of an industry. 2. The framework examines five key forces that determine an industry's long-run profitability: - Threat of new entrants - Bargaining power of buyers - Bargaining power of suppliers - Threat of substitute products - Rivalry among existing competitors 3. By analyzing these forces, companies can understand the competitive dynamics and profit potential of an industry. **Why Option A is incorrect**: Porter's Five Forces can be applied to new industries even without historical data. The framework is forward-looking and analytical, focusing on structural factors rather than historical performance. **Why Option B is incorrect**: Barriers to exiting an industry are related to the intensity of rivalry among existing competitors, not the threat of new entrants. Exit barriers (such as specialized assets, high fixed costs, or emotional attachments) keep companies competing even when profitability is low, increasing competitive intensity. **Key Points**: - Porter's Five Forces helps analyze industry attractiveness and competitive dynamics - It's applicable to both established and emerging industries - The framework focuses on structural factors that influence long-term profitability - Exit barriers affect rivalry intensity, not threat of new entrants
