When a brown compound of manganese (A) is treated with HCl it gives a gas (B). The gas taken in excess, reacts with NH_3 , to give an explosive compound (C). Identify compounds A, B and C.

A

`A= MnO_2, B = Cl_2, C = NCl_3`

B

`A= MnO, B =Cl_2, C = NH_4Cl`

C

`A=Mn_3O_4, B= Cl_2, C = NCl_3`

D

`A=MnO_3, B = Cl_2, C = NCl_2`
