| 
| A) | Due to regulation, a firm has little incentive to control costs as the costs can be shifted to consumers via a price increase. |  |  
| 
| B) | An existing firm in the industry is able to influence the regulatory board. |  |  
| 
| C) | Regulators prevent monopolists from making a profit. |  |  
 
 
 
Regulators do not seek to prevent monopolists from making a profit. Instead using average cost pricing, regulators will try to prevent monopolists from making a zero economic profit and ensure the monopolist a normal profit. Both remaining choices are reasons why regulations can fail.  |
