Which is not an outcome of rent ceilings? Select one:

A. black market rents below the rent-controlled prices

B. long waiting lists for rent-controlled housing

C. a shortage of rental housing

D. black market rents above the rent-controlled prices

E. a surplus of condominium housing

The answer it A, but i want to know why E is ture? Basically, in textbook said when the rent ceiling , the price ceiling set belowing market cleaning level, the shortage will happen. So why there also have surplus happen in option E ?

Please advise!

Thanks
