Which of these formulae is correct to find the gradient of the element k ?

A. <sub>k</sub> = ( frac{1}{V_k}( Sigma_{n leftarrow f&lt;k} Phi_n vec{S_n}- Sigma_{n leftarrow f&gt;k} Phi_n vec{S_n}) )
B. <sub>k</sub> = ( frac{1}{V_k}(- Sigma_{n leftarrow f} Phi_n vec{S_n}) )
C. <sub>k</sub> = ( frac{1}{V_k}( Sigma_{n leftarrow f} Phi_n vec{S_n}) )
D. <sub>k</sub> = ( frac{1}{V_k}(- Sigma_{n leftarrow f&lt;k} Phi_n vec{S_n}+ Sigma_{n leftarrow f&gt;k} Phi_n vec{S_n}) )
