Answer - B - Market equilibrium is reached when demand and supply are balanced so that both the amount of products sold and the market price are under no pressure to change.

Key Takeaway: Basically, the market equilibrium price is reached when the quantity demanded (noted as Q_d) is equal to the quantity that is supplied (Q_s). Because these are equal, there is no surplus or shortage of goods that would lead to a change in price.
