Solution

The correct option is B Oxygen
In ostwald process oxygen acts as an oxidizing agent to convert ammonia $N H_{3}$ to nitric acid $H N O_{3}$ .

$4 N H_{3} + 5 O_{2} 800^{o} C - ---- \to P t . g u a g e 4 N O + 6 H_{2} O + H e a t$

$N O$ reacts with $O_{2}$ to give $N O_{2}$

$2 N O + O_{2} 50^{o} C - -- \to 2 N O_{2}$

Further, $N O_{2}$ reacts with $O_{2}$ and $H_{2} O$ to give $H N O_{3}$ .
