the answer is A because lead has no reaction with alkalis and that is the main requirement for containers

Lead should be the Answer because it ia being fairly far down the activity series, and has no action with Alkalis 

Guys let's don't get confused
Actually, d correct answer is copper
Cause d question says Dat, "Conviniently stored", I.e for a long period of time
Lead would later react with NaOH after some time buh copper does not at all
Even in d text book, it is actually stated Dat lead doesn't react with alkali, fine, buh it is under ordinary conditions.?

Explanation:
Sodium hydroxide solution reacts with aluminium and zinc (theyβre amphoteric metals) and also attacks lead to form soluble plumbates. Copper, however, does not react with sodium hydroxide, so it can safely store the solution.
Why not the others?
Lead β β reacts with NaOH
Zinc β β reacts with NaOH
Aluminium β β reacts with NaOH
π― Final answer: D. Copper
