(C) The chemical reaction is: $P_4 + 3NaOH + 3H_2O \rightarrow PH_3 + 3NaH_2PO_2$. In this reaction,the oxidation state of phosphorus 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,this is a disproportionation reaction,which is a type of redox reaction.
