Solution

The correct option is D redox reaction
Reaction of Iron(III) oxide ( $F e_{2} O_{3}$ ) with carbon monoxide ( $C O$ ) to form iron ( $F e$ ) and carbon dioxide ( $C O_{2}$ ), is a redox reaction as both oxidation of carbon monoxide and reduction of iron is taking place. The equation can be written as: $F e_{2} O_{3} + 3 C O \to 2 F e + 3 C O_{2}$
