A data analyst is examining the correlation matrix of a new data set to identify issues that could adversely impact model performance. Which of the following is the analyst most likely checking for?

The correct answer is B. Multicollinearity. Examining a correlation matrix helps identify predictors that are highly correlated with each other, which can inflate variance in coefficient estimates and degrade model reliability - i.e., multicollinearity.
