for either intermolecular redox reaction or displacement reaction.

(C) The given reaction is: $4FeCr_2O_4 + 8Na_2CO_3 + 7O_2 \longrightarrow 2Fe_2O_3 + 8Na_2CrO_4 + 8CO_2$.In this reaction,the oxidation state of $Fe$ changes from $+2$ to $+3$ (oxidation) and the oxidation state of $O$ in $O_2$ changes from $0$ to $-2$ (reduction).Since two different reactants are undergoing oxidation and reduction,this is an intermolecular redox reaction.Therefore,the correct classification is an intermolecular redox reaction.

Assertion : When a metal is treated with conc. $HNO_3$,it generally yields a nitrate,$NO_2$,and $H_2O$.
Reason : Conc. $HNO_3$ reacts with a metal and first produces a metal nitrate and nascent hydrogen. The nascent hydrogen then further reduces $HNO_3$ to $NO_2$.
