Choose the figure which is different from the other three.

The correct answer is Option (4) → 

Compare the small shape with the big one. In three figures the inner shape is the same as the outer shape. In Option (4) a hexagon is drawn inside a circle, so it is the odd one out.

Option (1) — Incorrect. A triangle with a small triangle inside: the inner shape is the same as the outer one.

Option (2) — Incorrect. A pentagon with a small pentagon inside: the inner shape is the same as the outer one.

Option (3) — Incorrect. A hexagon with a small hexagon inside: the inner shape is the same as the outer one.
