The correct answer is B. Japan.
Japan is a resource-poor country and imports most of its raw materials, including iron ore and coking coal, for its iron and steel industry. In 2019, Japan imported 99.8% of its iron ore and 99.6% of its coking coal.
Britain, Poland, and Germany are all resource-rich countries and have their own domestic sources of iron ore and coking coal. In 2019, Britain produced 1.2% of its iron ore and 1.1% of its coking coal, Poland produced 3.6% of its iron ore and 1.3% of its coking coal, and Germany produced 1.8% of its iron ore and 0.8% of its coking coal.
Japan’s dependence on imported raw materials for its iron and steel industry makes it vulnerable to fluctuations in global commodity prices. In recent years, the price of iron ore has increased significantly, which has put pressure on the Japanese iron and steel industry.
