• D. None of the above

Answer 1

The correct option is A True

The statement is true.

$NaOH$ cant be stored in the vessel made of $Zn$ or $Al$ or $Be$.

Sodium hydroxide in contact with some metals (aluminium,bereyllium and zinc) reacts to produce flammable and potentially explosive hydrogen gas.

Aluminium is actually a very reactive metal that is unusual as it has layer of oxide ($A{l}_2{O}_3$) on the surface. This oxide is soluble in base forming an aluminate exposing the aluminum surface which then reacts.
