Does a scale represents the ration of the distance

The correct answer is D. Compared with the rest of the world, the United States' GDP is the largest on the planet. The United States is the world's largest national economy in nominal terms, with an estimated GDP of 15.7 trillion dollars (a quarter of nominal global GDP) and a fifth of global GDP in purchasing power parity.

Explanation:

The economy of the United States is a mixed capitalist economy, characterized by abundant natural resources, a developed infrastructure and high productivity. According to the International Monetary Fund, its GDP of US $ 15.7 billion constitutes 24% of the Gross World Product and about 21% of it in terms of purchasing power parity. This is the largest GDP in the world, although in 2008 it was 5% lower than the GDP of the European Union. It also has the sixth highest GDP per capita in the world.
