The OLS Estimators of the Coefficients in Multiple Regression Will

Multiple Choice

The OLS estimators of the coefficients in multiple regression will have omitted variable bias

A) only if an omitted determinant of Y_i is a continuous variable.
B) if an omitted variable is correlated with at least one of the regressors, even though it is not a determinant of the dependent variable.
C) only if the omitted variable is not normally distributed.
D) if an omitted determinant of Y_i is correlated with at least one of the regressors.
