31. Consider a reaction $\mathrm { aG } + \mathrm { bH } \rightarrow$ Products. When concentration of both the reactants G and H is doubled, the rate increases by eight times. However, when concentration of G is doubled keeping the concentration of H fixed, the rate is doubled. The overall order of the reaction is\\
(A) 0\\
(B) 1\\
(C) 2\\
(D) 3
