Which force describes the relationship between price and the quantity producers are willing to supply?

• A. Law of Diminishing Returns
• B. Law of Increasing Opportunity Cost
• C. Law of Demand
• D. Law of Supply

Answer: (D)

The relationship between price and the quantity producers are willing to supply is described by the Law of Supply. When the price of a good rises, producers can earn more revenue on each unit, which makes it worthwhile to produce and offer more of the good. Because higher output often requires using more resources or more expensive inputs, the marginal cost of producing additional units tends to rise, so only higher prices justify expanding supply. This incentive structure creates an upward-sloping supply curve, meaning quantity supplied increases as price increases, all else equal. The other ideas describe different dynamics. The Law of Diminishing Returns explains why adding inputs eventually yields smaller increases in output, not how price affects supply. The Law of Increasing Opportunity Cost is about the trade-offs and resource allocation that make some production choices more costly as you shift resources. The Law of Demand focuses on consumers—how price affects how much they want to buy, typically showing that higher prices reduce quantity demanded.
