Answer:
A)
regulate the company so its prices are fair
Step-by-step explanation:
Anti trust laws are used to limit the extent to which dominant players in an industry monopolize it for profit.
The aim is to regulate the conduct of businesses and promote competition.
One way this is achieved is by prohibition of price-fixing and operation of cartels that tend to control the market.
In the given example above two largest US manufacturers of athletic shoes and clothing want to merge.
The government can regulate their prices to make sure that they are fair. Market entry will not be difficult for new firms that want to enter the industry, and this will promote competition.
