Find the odd one out.

Logic : Both the triangles within the pentagon are the same at different positions.

So,

• Option - (1) :⇒ There is a gap of one place between the two triangles.
• Option - (2) : ⇒ There is a gap of one place between the two triangles.
• Option - (3) : ⇒ There is no gap between the two triangles.
• Option - (4) : ⇒ There is a gap of one place between the two triangles.

Here, Figure - (3) is the odd one out.

Hence, "Option - (3)" is the correct answer.
