Dumping in international trade is defined as:

• A. Imposing tariffs on imports
• B. Setting quotas on import volumes
• C. Providing subsidies to domestic producers
• D. Selling products in a foreign country at unsustainably low prices

Answer: (D)

Dumping occurs when a company sells goods in a foreign market at prices that are not sustainable there, often below its own production costs or below the price charged in its home market. The aim is to gain market share or push local competitors out, which is why this practice is viewed as unfair and is subject to anti-dumping rules. The other options describe different trade tools or policies: tariffs raise the price of imports, quotas limit how much can be imported, and subsidies to domestic producers are home-country support that can enable competitive pricing but do not define dumping itself.
