Oxidation and reduction (Redox)

(C) The reaction is: $P_4 + 3NaOH + 3H_2O \to 3NaH_2PO_2 + PH_3$. In this reaction,the oxidation state of phosphorus $(P)$ changes from $0$ in $P_4$ to $-3$ in $PH_3$ (reduction) and to $+1$ in $NaH_2PO_2$ (oxidation). Since both oxidation and reduction occur simultaneously,it is a disproportionation reaction,which is a type of redox reaction.
