What does a supply schedule depict?

A supply schedule is a tabular representation that illustrates the relationship between the price of a good or service and the quantity of that good or service that suppliers are willing to provide at those various price points. It effectively shows how much of a product will be supplied at different prices, indicating that as prices increase, typically, the quantity supplied also increases. This positive relationship is a fundamental concept in economics, reflecting suppliers' tendency to produce more when they can sell at higher prices due to the potential for greater profit.

The other options focus on different aspects of economic analysis: the correlation of demand and supply refers more broadly to market dynamics rather than the specifics of supply alone, the effect of price changes on consumer demand pertains to the demand side rather than supply, and variations in costs of production relate to supply but are not represented in a standard supply schedule, which focuses specifically on price and quantity supplied.
