for either intermolecular redox reaction or displacement reaction.

(C) In the reaction $Ca_{(s)} + 2H_2O_{(l)} \rightarrow Ca(OH)_{2(aq)} + H_{2(g)}$,the oxidation state of $Ca$ changes from $0$ to $+2$ (oxidation) and the oxidation state of $H$ in $H_2O$ changes from $+1$ to $0$ (reduction).This is a redox reaction where one element $(Ca)$ displaces hydrogen from water.Therefore,it is classified as a displacement reaction (specifically,a metal displacement reaction) and it is an intermolecular redox reaction.
