Assertion : Copper metal is turned green when exposed to atmospheric CO_(2) and moisture. Reason: Copper gets covered with a green layer of basic copper carbonate.

When a grey coloured object made of metal A is left exposed to damp air for a considerable time, it gets covered with a red-brown flaky coating by the process called B which eats up the whole object gradually. It is said that the presence of C and D is necessary for this process to take place. If this object is galvanised by metal E, then the process B does not occur. Name the metal A of which the object is made.
