With two independent variables, the best choice is a multiple regression model. Option D is a multiple regression model with Y as the dependent variable and X1 and X2 as the independent variables. This model allows for the examination of the relationship between Y and each independent variable separately while controlling for the other variable. The coefficients b1 and b2 represent the change in Y per unit change in X1 and X2, respectively, holding the other independent variable constant.
