Composition of German silver alloy is:

The correct answer is Option (4) → Cu, Zn, Ni

German silver contains no silver; it is named for its silvery colour. It is an alloy of copper, zinc and nickel, roughly Cu 25–30%, Zn 25–30% and Ni 40–50%; nickel gives it the silvery colour, and it contains no iron.

NCERT (Pre-rationalised edition, 2022-23):
Uses of Aluminium, Copper, Zinc and Iron – “… Zinc is used for galvanising iron. It is also used in large quantities in batteries, as a constituent of many alloys, e.g., brass, (Cu 60%, Zn 40%) and german silver (Cu 25-30%, Zn 25-30%, Ni 40-50%).”
