Upon heating`KCIO_(3)` in presence of catalytic amount of `MnO_(2)`, a gas `W` is formed. Excess amount of `W` reacts with white phosphours to given `X`. The reaction of `X` with pure `HNO_(3)` gives `Y` and `Z`.
Y and Z are, respectively

A

`N_(2)O_(4)` and `HPO_(3)`

B

`N_(2)O_(4)` and `H_(3)PO_(3)`
