Question

Select the odd one out of the following. (A) Iron (B) Copper (C) Steel (D) Aluminium

Answer 1

Answer: Steel

Explanation: All the things mentioned here are purely known as elements. They cannot be divided further into two heterogeneous materials. Due to this they are known to be in their pure state.

But Steel on the other hand is an alloy of Iron and Carbon along with other elements, due to which it can be divided into two or more heterogeneous materials or elements.

Hence Steel is the odd one out.
