Concept:
Odd-one-out questions are based on identifying a common pattern shared by most figures and spotting the one that violates it. The pattern may involve:
Orientation of shapes,
Relative position of dots,
Direction of arrows or triangles,
Consistency in arrangement.
Observation:
In Figures 1, 3, and 4:
The triangle and square follow a consistent relative orientation.
The dots are placed at corresponding corners with respect to the square.
In Figure 2:
The triangle is inverted in a manner inconsistent with the others.
The placement of dots does not follow the same positional pattern seen in the remaining figures.
Conclusion:
Since Figure 2 does not follow the common structural and positional pattern shared by the other figures, it is the odd one out.
Final Answer: \(\boxed{\text{Figure 2}}\)
