Which of the following often causes market failure -- that is, causes markets to fail to establish fair prices and use resources efficiently or properly? a. competition b. surpluses c. monopolies d. shortages reset

I would say monopolies.

Explanation:

I'm stuck on the same question but I'm going to go with monopolies because of my background knowledge and from what we learned in US history this year.
