Solution

The correct option is C iron oxide with $K_{2} O$ and $A l_{2} O_{3}$
Haber's process is used for the production of ammonia which is widely used for agricultural purposes that is for fertilisers.
$N_{2} + 3 H_{2} Δ - \to 2 N H_{3}$
And nowadays ( $F e O$ ) Iron oxide using as catalyst and $K_{2} O,$ $A l_{2} O_{3}$ using as promoters instead of $K O H$ .
