Refer to above diagram. Select the incorrect statement at 1000^oC. Given
$\begin{array}{r}2\mathrm{D}+{\mathrm{O}}_2\to 2\mathrm{DO},{\mathrm{\Delta G}}^{\ominus }=-370\mathrm{kJ}\\ 2\mathrm{C}+{\mathrm{O}}_2\to 2\mathrm{CO},{\mathrm{\Delta G}}^{\ominus }=-470\mathrm{kJ}\end{array}$
 

• A

  Reduction of DO is possible by C and metals are obtained in vapour state.

• B

  Reduction of DO is not possible by C

• C

  For reaction $\mathrm{DO}+\mathrm{C}\to \mathrm{D}+\mathrm{CO},\mathrm{\Delta }{G}^{\mathrm{\Theta }}=+50\mathrm{kJ}$

• D

  Metal C has more affinity for O₂ as compared to D.
