Solution

The correct option is A $Δ G$ with temperature
Ellingham Diagram is diagrams which help us in predicting the feasibility of thermal reduction of ore.

Ellingham diagram normally consists of plots of $Δ G$ vs $T$ for the formation of oxides of common metals and reducing agents i.e., for the reaction shown below,

$2 x M (s) + O_{2} (g) \to 2 M_{x} O$

Hence, options A is the correct answer.
