Final answer:
Option (d), The United Kingdom is the most popular target for U.S.-based franchises to enter the global market, due to cultural, language, and historic business alignment.
Step-by-step explanation:
The most popular target country for U.S.-based franchises to enter the global market is the United Kingdom. According to data, the UK shows significant interest in American franchises, as evidenced by the presence of numerous fast-food restaurants and the influence of American culture. Products and services from the U.S. such as fast food, computers, news networks, and Hollywood movies have become the products of choice in the UK, with recognizable brands like McDonald's operating successfully in the market.
Despite the large populations of China and India and their growing economic influence, the cultural and linguistic alignment between the United States and the United Kingdom makes the UK a more accessible and attractive market for US franchises. The historical ties and similar business practices between the two nations further facilitate the entry of U.S. franchises into the UK market.
