According to the World Bank (WB), what is the requirement to be in the "developing nation" category? A country must be classified as low-income. A country must have a low- or middle-income. A country must have an industrialized economy. A country must be voted into the "developed" category.

Respuesta :

"A country must have a low- or middle-income" is the correct response since when nations are developing there is almost never an upper class due to a lack of revenue.
