Which statement best describes the interaction of supply and demand in determining price?

• A. Demand is the quantity buyers want at various prices.
• B. Supply and demand interact to determine price where they meet.
• C. Price is determined by government in most cases.
• D. Demand determines supply.

Answer: (B)

In a market, price forms from the interaction between buyers and sellers. The best statement says price emerges at the point where the amount sellers are willing to supply at a given price equals the amount buyers want to purchase at that price. That intersection creates the equilibrium price and quantity, and it’s where the market tends to settle. Think of it as a balancing act: when prices rise, producers have more incentive to supply, and some buyers pull back, which moves the market toward the equilibrium. When prices fall, demand rises and supply may slow, again guiding the market toward equilibrium. If there’s more demand than supply, prices tend to go up; if there’s more supply than demand, prices tend to fall. The other statements don’t fit the full picture. Focusing only on demand ignores how suppliers respond to price signals. Saying government sets the price is not typical in a free market; price is mainly determined by the forces of supply and demand. And claiming demand determines supply suggests one-way causation, when in fact both sides influence price through their responses to it.
