Question

Group the given figures into three classes using each figure only once.

• A. 7,8,9 ; 2,4,3 ; 1,5,6
• B. 1,3,2 ; 4,5,7 ; 6,8,9
• C. 1,6,8 ; 3,4,7 ; 2,5,9
• D. 1,6,9 ; 3,4,7 ; 2,5,8
• E. 1,6,9 ; 3,4,8 ; 2,5,7

Answer 1

The Correct Option is D

Concept: This is a
classification (visual reasoning) problem based on:

• Number of sides
• Type of geometric shapes
• Structural similarities

Step 1: Observe all figures.
Each figure represents a polygon with varying number of sides and shapes.
Step 2: Group based on similarity.

• 
  Group 1 (Triangles): 1, 6, 9 (All have 3 sides)
• 
  Group 2 (Quadrilaterals): 3, 4, 7 (All have 4 sides)
• 
  Group 3 (Irregular/complex shapes): 2, 5, 8 (More than 4 sides or irregular structure)

Step 3: Match with options.
Only one option correctly represents this grouping.
Step 4: Option analysis.

• (A) Incorrect grouping $\times$
• (B) Mixed categories $\times$
• (C) Incorrect classification $\times$
• (D) Correct grouping \checkmark
• (E) Misplaced figures $\times$

Conclusion:
Thus, the correct answer is
Option (D).
