Copper becomes green when exposed to moist air for a long period. This is due to :
(a) the formation of a layer of cupric hydroxide on the surface of copper.
\( P \)
(b) the formation of a layer of basic carbonate of copper on the surface of copper.
(c) the formation of basic copper sulphate layer on the surface of the metal.
W
(d) the formation of a layer of cupric oxide on the surface of copper.
