For the reaction $\mathrm{H}_{2} \mathrm{O}(\mathrm{g})+\mathrm{C}$ (graphite) $\leftrightharpoons \mathrm{CO}(\mathrm{g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{g})$, the variation of energy parameter $\Delta \mathrm{G}^{\mathrm{0}}$, $\Delta \mathrm{H}^{\mathrm{0}}$ and $\mathrm{T} \Delta \mathrm{S}^{\mathrm{0}}$ of the reaction over a large temperature range is shown below. The correct identification of the curves is given by
(a)$\mathrm{A} \rightarrow \Delta \mathrm{G}$, $\mathrm{B} \rightarrow \Delta \mathrm{H}$, C→TAS
(b)$\mathrm{A} \rightarrow \Delta \mathrm{H} , \mathrm{B} \rightarrow \Delta \mathrm{G}, \mathrm{C} \rightarrow \mathrm{T} \Delta \mathrm{S}$
(c)$\mathrm{A} \rightarrow \Delta \mathrm{G} . \mathrm{B} \rightarrow \mathrm{T} \Delta \mathrm{S}, \mathrm{C} \rightarrow \Delta \mathrm{H}$
(d)$\mathrm{A} \rightarrow \mathrm{TAS}, \mathrm{B} \rightarrow \Delta H, \mathrm{C} \rightarrow \Delta \mathrm{G}$
