Vedclass · Answer

(D) German silver is an alloy composed of Copper $(Cu)$,Zinc $(Zn)$,and Nickel $(Ni)$.Brass is an alloy composed primarily of Copper $(Cu)$ and Zinc $(Zn)$.Comparing the two,Copper $(Cu)$ and Zinc $(Zn)$ are common to both alloys.Iron $(Fe)$ is not a primary component of either,but Nickel $(Ni)$ is present in German silver and is not a standard component of brass.Therefore,the metal that is not common to both is Nickel $(Ni)$.Hence,option $(D)$ is the correct answer.
