When cities prevent landlords from charging market rents, which of the following are common long-run outcomes?
a. the quantity of available rental housing units falls.
b. the quality of rental housing units falls.
c. black markets develop.
d. the future supply of rental housing units increases.

b. and c.

Explanation:

Based on the information provided within the question it can be said that this will cause the quality of rental housing units to fall and the development of Black Markets. This can be said because not being able to charge market rents will cause landlords to abandon maintenance of their housing units as it will be an extra expense for them. Secondly, history has shown that when government officials prevent something sooner or later a black market will develop in order to provide a supply for the demand.
