Which of these is the non-conservative differential form of Eulerian x-momentum equation?

• A. \(\frac{\partial(\rho u)}{\partial t}+\nabla.(\rho u\vec{V})=-\frac{\partial p}{\partial x}+\rho f_x\)
• B. \(\rho\frac{Du}{Dt}=-\frac{\partial p}{\partial x}+\rho f_x\)
• C. \(\frac{(\rho u)}{\partial t}=-\frac{\partial p}{\partial x}+\rho f_x\)
• D. \(\rho \frac{\partial u}{\partial t}=-\frac{\partial p}{\partial x}+\rho f_x\)
