# German silver does not have silver in it,its composition is

$(a)\;\text{ Copper 35%,zinc 25% and Ni 55%} \\(b)\;\text {Copper 45%,zinc 25% and Ni 20%} \\(c)\;\text{Copper 50%,zinc 19% and Ni 30%} \\ (d)\;\text{Copper 25%,zinc 25% and Ni 50%}$

German silver varies in composition, the percentage of the three elements ranging approximately as follows: copper, from 50% to 61.6%; zinc, from 19% to 17.2%; nickel, from 30% to 21.1%.
This mixture looks like silver, therefore, called German silver.
Hence c is the correct answer.
