Answer:
Here the correct answer is C)
Step-by-step explanation:
Inferior goods can be described as those goods whose demands decreases , when the income of the customers increases. These goods are related to negative income elasticity, they have inverse relationship with price.
Price elasticity of supply is infinite means that there will be change in the price and goods would be supplied at one or same price only. The graph of this price elasticity of supply would be horizontal.
In the given above question it is quite clear that macaroni and cheese are inferior goods and their price elasticity of supply is infinite ( means they will be supplied at same or one price ).
