B. supply curve

Explanation:

You are presenting a graph of the balance between demand and supply, but only the demand curve is being presented. This is missing the supply curve.

Supply and demand are the two forces that guarantee the functioning of a market, determining prices and the quantity of products offered. The term supply refers to the available quantity of a product, that is, what companies want or can sell. Demand, on the other hand, is the amount that consumers want or can buy from this product, that is, their demand.
