Answer:
B) issue a complaint stating that the business is in violation of the law.
Step-by-step explanation:
The Robinson-Patman Act prohibits seller from practicing price discrimination, that means that they sell their products to different buyers at different prices. This law applies only to the sale of goods, and the goods sold to the different buyers must be similar and the buyers must also be in similar conditions. E.g. it is not illegal to sell at different prices if one buyer is located next to the factory while the other is located 3,000 miles away, in this case the cost of transportation accounts for the difference in price.
Also, price discrimination must result in injury to the buyer, which means that there business is being harmed because their direct competitors receive the product at a lower price. E.g. if a seller charges Walmart a lower price than it charges Target, Target will be forced to sell at a higher price which may result in lower sales.
Finally, since this is a federal law, it generally applies to interstate commerce. Domestic commerce is covered by state laws and state entities.
