B)Y = X + U.
C)Y = βX + U.
D)Y = Xβ + U.

The multiple regression model is typically written in matrix form as Y = Xβ + U. Here, Y represents the dependent variable (or outcome), X is the matrix of independent variables (or predictors), β is the vector of regression coefficients, and U is the vector of error terms (or residuals). Therefore, the correct choice is D, which matches this standard form of the multiple regression model.
