The Brainliest Answer!
In all options, the first material is an alloy and the rest are its constituents.
But in option 1, the constituent of brass is written as copper and tin. It is wrong. Brass is made of copper and zinc. So it is the incorrect match.
Copper and tin make bronze.
So answer is option 1.
