What Is the Long Run Solution to the Following Dynamic $\Delta$

Multiple Choice

What is the long run solution to the following dynamic econometric model? $\Delta$ y_t = $\beta$ ₁ + $\beta$ ₂ $\Delta$ X_2t + $\beta$ ₃ $\Delta$ X_3t + u_t

A) y = $\beta$ ₁ + $\beta$ ₂X₂ + $\beta$ ₃X₃
B) y_t = $\beta$ ₁ + $\beta$ ₂X_2t + $\beta$ ₃X_3t
C) y = - ( $\beta$ ₂/ $\beta$ ₁) X₂ - ( $\beta$ ₃ / $\beta$ ₁) X₃
D) There is no long run solution to this equation
