Case-Based-IV: Reactive metals like \( \mathrm{Na} \) and \( \mathrm{K} \) react with water with liberation of \( \mathrm{H}_{2} \) gas and form corresponding hydroxides while the metals \( \mathrm{Mg}, \mathrm{Zn}, \mathrm{Al} \) and \( \mathrm{Fe} \) are low in reactivity to react with cold water but they will only react with steam when red hot form corresponding oxides.

Which of the following metal do not react with cold water?
a. \( \mathrm{Na} \)
b. \( \mathrm{Fe} \)
c. \( \mathrm{Mg} \)
d. \( \mathrm{Ca} \)
