Pyrolusite ore on oxidation with `KCIO_(3)//KNO_(3)` in basic medium produces dark green coloured compound `(A)`, which on electrolysis produces a purple coloured compound `(B)`. The purple coloured rhombic prisms. It shows different reactions in different mediums.
Excess of compounds (B) on heating with conc. `H_(2)SO_(4)` gives an explosive oil (C ), which on heating decomposes to gives another compound (D ) along with oxygen.
When (D) reacts with `PbO_(2)//HNO_(3)` it produces a purple`//` pink coloured compound (E). Identify (E)
A. `NaMnO_(4)`
B. `Mn(OH)_(2)`
C. `HMnO_(4)`
D. `Na_(2)MnO_(4)`
