Solution

The correct option is A thermite reaction
The reaction of Iron (III) oxide ( $F e_{2} O_{3})$ with aluminium, is used to join railings of railway tracks or cracked machine parts. This reaction is known as the thermite reaction.
$2 A l + F e_{2} O_{3} \to A l_{2} O_{3} + 2 F e + H e a t$
$2 A l + C r_{2} O_{3} \to A l_{2} O_{3} + 2 C r + H e a t$
