Answer 2

Answer:

Brass is the odd one out.

Explanation:

An element is a ‘substance’ made of atoms of a particular kind only. It does not have any other substance mixed with it.  

Elements have a specific boiling and melting point. An element is represented by a symbol. Copper, platinum, zinc are all metallic elements.

An alloy is a ‘mixture of elements’ usually metals combined in particular ratios. An alloy cannot be represented by a symbol or formula. Brass, bronze are examples of alloys. Since ‘brass’ is an ‘alloy’ and the rest are all elements it is the ‘odd one out’.
