View answer and explanation
Correct option: D
Cr2O3+2Al→ΔAl2O3+2CrC{r_2}{O_3} + 2Al\xrightarrow{\Delta }A{l_2}{O_3} + 2Cr
Option D (Cr2O3+2Al→ΔAl2O3+2CrC{r_2}{O_3} + 2Al\xrightarrow{\Delta }A{l_2}{O_3} + 2Cr) is correct because aluminum displaces chromium from its oxide, which is a metal displacement reaction.
