Find the odd figure among the four given figures.

The correct answer is Option (1) → 

Count all the straight lines (the sides and the lines inside). Three figures are made of seven straight lines each. Option (1) has six, so it is the odd one out.

Option (2) — Incorrect. A triangle with four lines drawn inside: three + four = seven straight lines.

Option (3) — Incorrect. A hexagon with one line drawn inside: six + one = seven straight lines.

Option (4) — Incorrect. A pentagon with two lines drawn inside: five + two = seven straight lines.
