Solution:

Concept- An alloy is a mixture of two or more metals. They may also result from the fusion of metals with other elements. However, compared to the individual qualities of these components, alloys display differing features. Alloys are tougher and stronger when compared to pure metals.
Stainless steel consists of iron and carbon specifically with Cr (16-26%) and Ni (35%). It is used in building industries due to its durability.
Duralumin is an alloy of Al (95%) and Cu (4%) mainly with other metals. It is used in aircraft and truck wheels where good strength is needed,
German silver is an alloy of Cu (60%), Zn (20%) and Ni (20%). It has a colour of silver. Thus the name German silver. It is used in jewellery and in making musical instruments.
Hence, the correct answer is option 3.
