Consider the following stencil. Assume a uniform grid. What is the convective flux at the western face (\(\dot{m_w}\phi_w\)) using the FROMM scheme?

• A. \((\phi_P-\frac{\phi_E}{4}+\frac{\phi_W}{4}) max⁡(\dot{m_w},0)-(\phi_W\frac{-\phi_{WW}}{4}+\frac{\phi_C}{4}) max⁡(-\dot{m_w},0)\)
• B. \((\phi_P-\frac{\phi_W}{4}+\frac{\phi_E}{4}) max⁡(\dot{m_w},0)-(\phi_W\frac{-\phi_{WW}}{4}+\frac{\phi_C}{4}) max⁡(-\dot{m_w},0)\)
• C. \((\phi_P\frac{-\phi_E}{4}+\frac{\phi_W}{4}) max⁡(\dot{m_w},0)-(\phi_W\frac{-\phi_C}{4}+\frac{\phi_{WW}}{4}) max⁡(-\dot{m_w},0)\)
• D. \((\phi_P\frac{-\phi_W}{4}+\frac{\phi_E}{4}) max⁡(\dot{m_w},0)-(\phi_W\frac{-\phi_C}{4}+\frac{\phi_{WW}}{4})max⁡(-\dot{m_w},0)\)
