Answer:
D. Dumping
Step-by-step explanation:
Dumping is a term associated in trade between two or more nations (international trade). It occurs when a country or company export product to another country at a price that is lower in foreign importing market than the price in the exporter's domestic market and also when the exporter is selling for a price that is lower than the cost of production. It creates a form of unfair competition as products are being sold at a price that does not accurately reflects their cost.
In this case, the US apple growers were injuring the pricing of apple in the Mexican market by selling below production cost.
