When white phosphorous reacts with `NaOH`, it produces a gaseous mixture by the following parallel reaction.
`P_(4) +3NaOH +3H_(2)O rarr 3NaH_(2)PO_(2)+PH_(3)uarr`
`3P_(4)+8NaOH +8H_(2)O rarr 8NaH_(2)PO_(2)+2P_(2)H_(4)uarr`
The correct thermal stability order is
A. `PH_(4)Cl gt PH_(4)Cl gt PH_(4)I`
B. `PH_(4)I gt PH_4)Cl gt PH_(4)Br`
C. `PH_(4)Br gt PH_(4)Cl gt PH_(4)I`
D. `PH_(4)I gt PH_(4)Br gt PH_(4)Cl`
