Question

Select the alternative which represents three out of the five alternative figures which, when fitted into each other, would form a complete square.

• A. 123
• B. 124
• C. 135
• D. 145
• E. 142

Answer 1

The Correct Option is D

Concept: This is a
figure formation (visual reasoning) problem involving:

• Combining given pieces to form a complete square
• Matching edges and angles
• Avoiding gaps and overlaps

Step 1: Identify square-forming conditions.
To form a square:

• Outer boundary must be straight
• Internal edges must fit without gaps
• Angles should complement each other (mostly right angles)

Step 2: Analyze usable pieces.

• Figures (1), (4), and (5) have edges that can align to form straight boundaries
• Their shapes complement each other to complete a square

Step 3: Reject incompatible pieces.

• Figures (2) and (3) introduce irregular extensions
• These prevent proper square formation

Step 4: Option analysis.

• (A) 123: Cannot form square $\times$
• (B) 124: Incomplete fit $\times$
• (C) 135: Misfit edges $\times$
• (D) 145: Perfect square formation \checkmark
• (E) 142: Leaves gaps $\times$

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