An oragne colour solid (A) on heating gives a colourless gas (B) and colourless vapours (C) which on condensatio gives a colourless neutral liquid and a green residuce (D) which is a metal oxide. Gas - B gives a pungent odoured gas when reacts with hydrogen catalytically. Neutral liquid above formed converts anhydrous copper sulphate to blue
Gas 'B' in the above paragraph is ........

A

`H_2`

B

`O_2`

C

`N_2`

D

`Cl_2`
