Answer:
A. emergency plumber services and C.insulin.
Step-by-step explanation:
From the list provided the best candidates for this would be emergency plumber services and insulin. That is because these are items or services that have a high supply but low demand due to the population of customers being a minority. This, therefore, causes market inefficiency which leads to deadweight loss. Other items like Coca-Cola and food mostly stay in equilibrium because products are made depending on the current demand and the customer population is the vast majority.
