Solution

The correct option is B Platinum
$4 {NH}_{3} (g) + 5 O_{2} (g) P t - -- \to 800 ° C 4 NO (g) + 6 H_{2} O (g)$
The above reaction shows Ostwalds's process, used for manufacturing nitric acid industrially. Catalysts are generally used to increase or decrease the rate of a reaction. However, they do not take part in the chemical reaction. Platinum is used as a catalyst to speed up this reaction.
