What is the primary product of Haber-Bosch process?

The correct option is A Ammonia
In Haber-Bosch process $N_2\left(g\right)$ and $H_2\left(g\right)$ are reacted at a high temperature of $723K$ and $20265kPa$ pressure in presence of iron-bed catalysts $F{e}_3{O}_4$ mixed with ​
$K_{2}O,Si{O}_2,$ and $A{l}_2{O}_3$ to produce $N{H}_3\left(g\right)$. It is an exothermic process which takes place in accordance with Le Chatelier’s principle.
$N_2\left(g\right)+3H_2\left(g\right)\stackrel{\Delta }{\rightleftharpoons }2N{H}_3\left(g\right)$
