$A$ tetra-atomic molecule $(A)$ on reaction with nitrogen $(I)$ oxide,produces two substances $(B)$ and $(C).$ $(B)$ is a dehydrating agent in its monomeric form while substance $(C)$ is a diatomic gas which shows almost inert behaviour. The substances $(A)$,$(B)$,and $(C)$ respectively will be

• A
  $P_4, P_4O_{10}, N_2$
• B
  $P_4, N_2O_5, N_2$
• C
  $P_4, P_2O_3, Ar$
• D
  $P_4, P_2O_3, H_2$
