B. $$\left( {\frac{{{\partial ^3}G}}{{\partial {X^3}}}} \right) = 0$$
C. $$\left( {\frac{{{\partial ^2}G}}{{\partial {X^2}}}} \right) + \left( {\frac{{{\partial ^3}G}}{{\partial {X_3}}}} \right) = 0$$
D. $$\left( {\frac{{{\partial ^2}G}}{{\partial {X^2}}}} \right) - \left( {\frac{{{\partial ^3}G}}{{\partial {X^3}}}} \right) = 0$$
