Market equilibrium is the economic principle that describes the state where supply and demand are balanced, resulting in an effective price for goods and services. At this point, the quantity of goods that producers are willing to supply matches the quantity that consumers are willing to purchase, leading to an efficient allocation of resources in the market. When supply exceeds demand, prices tend to fall, and when demand exceeds supply, prices typically rise, which helps to restore balance. Thus, it highlights the dynamic interaction between supply and demand in determining prices and quantities in the marketplace, demonstrating how market forces work together to achieve equilibrium.

The other options—opportunity cost, supply elasticity, and consumer surplus—focus on different aspects of economic theory. Opportunity cost relates to the value of the next best alternative foregone when making a choice. Supply elasticity measures how responsive supply is to changes in price, and consumer surplus refers to the difference between what consumers are willing to pay for a good versus what they actually pay. While relevant, these concepts do not directly explain the interaction between supply and demand as effectively as market equilibrium does.
