Exposure to environmental pollution is most highly correlated with which of the following factors?

A) social class
B) income
C) race
D) education
E) gender

Research has consistently shown that communities of color tend to have higher levels of exposure to environmental pollution compared to white communities, indicating that race is the most highly correlated factor with environmental pollution. This is often a result of systemic racism and economic inequality. While social class, income, education, and gender can also be factors in exposure to pollution, they are not as strongly correlated as race.
