Which variable combination is most correlated and could potentially support feature reduction?

Explanation

RAD and TAX have a correlation of -0.95, the largest absolute correlation among the listed pairs. This very strong inverse linear relationship suggests the variables may contain overlapping predictive information, making them candidates for feature reduction.
