Find the odd figure among the four given figures.

The correct answer is Option (1) → 

Compare the small shape with the big one. In three figures the inner shape is the same as the outer shape. In Option (1) a square is drawn inside a triangle, so it is the odd one out.

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

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

Option (4) — Incorrect. A square with a small square inside: the inner shape is the same as the outer one.
