A highly developed country is best described as:
a) Countries with low rates of population growth and high per person incomes.
Countries that are considered highly developed typically have a strong economy, advanced technological infrastructure, and high living standards. One clear indicator of a highly developed country is its high per capita income, which suggests that individuals in these countries tend to have a greater quality of life and access to resources. Additionally, low rates of population growth often reflect a stable society where individuals have access to education and healthcare, contributing to the overall well-being of the population.
