A will reduce BO below T1 and B will reduce AO above T1 . At higher temperature gases have lower free energy, hence BO should be gas.

According to ellingham diagram option B is right
See lessOption B according to Ellingham diagram
Option B according to Ellingham diagram
See lessCorrect answer is option B. The slope of the ellingham diagram is -(delta)S. And we know that, entropy is proportional to gaseous species. BO must be a gaseous species then only its slope will be negative.
