Answer»

<P>redox reaction ,-3 and -5
redox reaction , +3 and +5
disproportionation reaction ,-3 and +1
disproportionation reaction , -3 and +3

Solution :`3CI_(2)rarr6NaOHrarr5NaCI+NaH_(2)PO_(2)`
O.N of in `P_(4)` decreases FORM 0 to -3 in `PH_(3)` and INCREASES from 0 to +1 in `NaH_(2)PO_(2)` therefore it is a disproportionation reaction
