Answer:
B) countries with higher GDP per person tend to have healthier environments.
Explanation:
According to the 2020 Environmental Performance Index (EPI) elaborated by Yale and Columbia universities, a strong positive correlation exists between high GDP per capita and healthier environments. There are a few exceptions to this correlation, in Asian (especially Arab) countries where GDP per capita might be high, but the vast majority of income is received by a vary small number of people. But in the rest of the world, a high GDP per capita generally results in healthier environments.
