Vedclass · Answer

(C) German silver consists of $Cu$,$Zn$,and $Ni$. This is correctly matched.Alnico consists of $Fe$,$Al$,$Ni$,and $Co$. This is correctly matched.Monel metal consists of $Ni$ and $Cu$ (often with small amounts of $Fe$ and $Mn$). It does not contain $Zn$ or $Sn$. Therefore,$Cu + Zn + Sn$ is incorrect; this composition actually represents Gun metal.Duralumin consists of $Al$,$Cu$,$Mg$,and $Mn$. This is correctly matched.Thus,the wrongly matched option is $C$.
