C)Statistically independent and correlated with one another.
D)Statistically dependent and correlated with one another.

The independence assumption requires that the independent variables in a multiple regression model are statistically independent and uncorrelated with one another. If the independent variables are correlated with each other, it can lead to multicollinearity which can cause problems in the interpretation of the coefficients and the overall significance of the model. Therefore, researchers must ensure that the independent variables are independent and uncorrelated before running a multiple regression.
