Explanation

German Silver is primarily an alloy of Zinc and Copper (Zn + Cu), often with Nickel added for color. Option A represents the core components commonly cited in relation to German Silver's composition. Option B is incorrect because it omits the necessary copper component or misrepresents the primary alloying elements. Option C is incorrect because while nickel is present, this combination does not represent the standard definition of German Silver. Option D is incorrect as tin is not a primary component used to define German Silver.
