A non-metal A which is the largest constituent of air, when heated with \[{{H}_{2}}\] in 1: 3 ratio in the presence of catalyst (Fe) gives a gas B. On heating with \[{{O}_{2}}\] it gives an oxide C. If this oxide is passed into water in the presence of air it gives an acid D which acts as a strong oxidizing agent. Identify A, B, C and D

A) \[A-{{N}_{2}},\,\,B-HN{{O}_{3}},\,\,C-NO,D-N{{H}_{3}}\]

B) \[A-{{N}_{2}},\,\,B-N{{H}_{3}},\,\,C-NO,D-HN{{O}_{3}}\]

C) \[A-{{N}_{2}},\,\,B-NO,\,\,C-HN{{O}_{3}},D-N{{H}_{3}}\]

D) \[A-{{N}_{2}},\,\,B-HN{{O}_{3}},\,\,C-N{{H}_{3}},D-NO\]

E) None of these
