Which acid dissolves iron but doesn't attack copper, silver, or zinc?

Q. Hi I am Vikas , I want to know which acid can dissolve iron but does not dissolve copper, silver and zinc.

Hi, Vikas. I am not sure that there is any such acid, and zinc is an extremely active metal.

Please put your situation into context rather than casting it in the abstract. Thanks.
