Form the continuity equation for steady 2-dimensional flow when the x-direction grids are stretched.Density → ρx and y-velocities → u,vCoordinates in physical domain → x,yCoordinates in computational domain → ξ, η.

• A. \(e^\eta\frac{\partial(\rho u)}{\partial\xi}+\frac{\partial(\rho v)}{\partial\eta}\)
• B. \(\frac{\partial(\rho u)}{\partial\xi}+e^\xi\frac{\partial(\rho v)}{\partial\eta}\)
• C. \(\frac{\partial(\rho u)}{\partial\xi}+e^\eta\frac{\partial(\rho v)}{\partial\eta}\)
• D. \(e^\xi\frac{\partial(\rho u)}{\partial\xi}+\frac{\partial(\rho v)}{\partial\eta}\)
