Question

when quantity supplied equals quantity demanded, there is:
a. excess quantity demanded.
b. excess quantity supplied.
c. disequilibrium.
d. a market - clearing price (equilibrium price).

Explanation:

When the quantity supplied matches the quantity demanded, the market reaches a state where there is no surplus or shortage. This corresponds to the equilibrium price, which is also called the market-clearing price because it "clears" the market of excess supply or demand. Options a, b, and c describe situations where supply and demand are not equal.

Answer:

d. a market-clearing price (equilibrium price)
