# Which metal is obtained commercially by the electrolysis of salt?

$(a)\;Zn \\(b)\;K \\(c)\;Fe \\ (d)\;Ag$

'K' is obtained commercially by the electrolysis of salt
Metals, including K, occur as compounds in nature. The pure, uncombined form of these metals results from commercial electrolysis of salt.
Hence b is the correct answer.
