Final answer:
A corporation incorporated in another country but operating in the U.S. is called an (D) alien corporation.
Step-by-step explanation:
A corporation in the United States that has been incorporated in another country is referred to as a(n) alien corporation. This distinguishes it from a domestic corporation, which is incorporated within the United States, and a foreign corporation, which refers to a company doing business in a state other than its state of incorporation but within the United States. An alien corporation may engage in business and earn income in the U.S., such as selling imported goods and earning U.S. dollars. However, it has to deal with the laws, taxes, customs, and culture of both the U.S. and its home country.
In the context of global business, when a large corporation operates manufacturing or service companies in various countries, it becomes known as a multinational. These multinational companies contribute to the country's GDP, circular flow, and business cycle but also encounter challenges such as repatriating earnings back to their home country or dealing with globalization trends like the relocation of manufacturing from the U.S. to countries like China.
