Find the odd figure among the four given figures.

The correct answer is Option (1) → 

Compare the sides of the two shapes. In three figures the inner shape has one more side than the outer shape. In Option (1) the outer hexagon has six sides and the inner pentagon has five sides, so it is the odd one out.

Option (2) — Incorrect. A square with a small pentagon inside: four sides outside and five sides inside, one more inside.

Option (3) — Incorrect. A triangle with a small square inside: three sides outside and four sides inside, one more inside.

Option (4) — Incorrect. A pentagon with a small hexagon inside: five sides outside and six sides inside, one more inside.
