A
Omitted variable bias occurs when the omitted variable is correlated with an included regressor and is a determinant of the dependent variable.
B
Omitted variable bias occurs when the omitted variable is correlated with an included regressor but is not a determinant of the dependent variable.
C
Omitted variable bias occurs when the omitted variable is independent of an included regressor and is a determinant of the dependent variable.
D
Omitted variable bias occurs when the omitted variable is independent of an included regressor but is not a determinant of the dependent variable.
