Answer:
d. Market clearing price will fall, and equilibrium quantity will fall.
Explanation:
Inferior goods are those goods which do not behave normally to market.
As with increase in consumer spending capacity, their demand decreases.
Accordingly with decrease in demand , the prices will fall.
Thus, either Statement b is correct or statement d.
Since demand and price both tend to fall, the equilibrium quantity will fall for the same, as the demand will be low, the equilibrium quantity will fall to meet the demand level.
Thus, Statement D is correct.
