Question

Out of the four materials listed, three are alike in some manner and one is different. Select the odd one.

A.

Iron

B.

Gold

C.

Steel

D.

Silver

Correct option is C

The odd one out is C. Steel.

Logic:

Iron, Gold, and Silver are pure elements found naturally in the periodic table (metals).
Steel, on the other hand, is an alloy made by combining iron with other elements like carbon. It is not a pure element.
Thus, Steel is different from the others.
