(B) The chemical equation for the reaction is: $P_4 + 3NaOH + 3H_2O \to PH_3 + 3NaH_2PO_2$In this reaction,the oxidation state of phosphorus changes from $0$ in $P_4$ to $-3$ in $PH_3$ (reduction) and $+1$ in $NaH_2PO_2$ (oxidation).Since the same element is simultaneously oxidized and reduced,this is a disproportionation reaction.
