(D) Most metals do not react with $NaOH$. However,amphoteric metals like $Zn$,$Al$,and $Pb$ react with strong bases like $NaOH$ to evolve $H_2$ gas.For example,the reaction for $Zn$ is:$Zn + 2NaOH \rightarrow Na_2ZnO_2 + H_2 \uparrow$$Mg$,$Ba$,$Ca$,and $Sr$ are alkaline earth metals and do not react with $NaOH$ to produce $H_2$ gas.

Which of the following metals will give $H_2$ gas on reaction with $NaOH$?
