Final answer:
The United States is a major participant in intra-industry international trade, particularly in the auto industry, where it is both a substantial exporter and importer, making it the largest importer but not the largest exporter. Correct option is b)
Step-by-step explanation:
The United States is a key player in international trade, and according to the theory of comparative advantage, it is involved in both exporting and importing goods, notably in the intra-industry trade. The United States both produces and exports autos and imports them, illustrating its substantial role as an exporter and an importer in the same industry. The U.S. Census Bureau reported that in 2021, the United States exported $131 billion worth of autos and imported $317 billion worth, indicating a significant balance of trade activities within the automotive sector. Given this data, the correct answer to where the United States stands as a participant in international trade is option (b) It is the largest importer but not the largest exporter.
