Solution

The correct option is B False
Alkali and alkaline earth metals react with water to produce hydrogen gas and a metal hydroxide.
This is due to their high electropositive character.
${Mg}_{(s) +} H_{2} O_{(aqu) \to} Mg {(OH)}_{2}_{(s)} + H_{2_{(g)}}$
Therefore, the hydrogen cannot be produced from alkalis by chemical reaction is a false statement.
