Which country’s development into an economic power is known as the ”Miracle on the Han River”?

The correct option is South Korea.

The term "Miracle on the Han River" refers to the period of rapid economic growth and industrialization in South Korea following the Korean War (1950–1953). During this time, South Korea transformed from a war-torn, agrarian nation into a highly developed global economic powerhouse and a major technological hub.

The phrase is named after the Han River, which flows through the capital city of Seoul, symbolizing the country's national rebirth and spectacular rise. This economic transformation was driven by export-oriented industrialization, heavy investment in education and infrastructure, and the rise of major family-owned conglomerates known as chaebols (such as Samsung, Hyundai, and LG).
