Question

On the left are pieces of a jigsaw puzzle. Identify the image (A–D) that can be reproduced using all the pieces shown.

• A. A
• B. B
• C. C
• D. D

Hint:

When a set has one curved edge, first test every option by placing that curve; if any corner/edge then needs a second curve, discard the option immediately.

Answer 1

The Correct Option is A

1) Catalogue the puzzle pieces.
There is one curved quarter–disc (an arc with a radius matching the square’s corner), two isosceles triangles, and one trapezium/quad with a long straight edge.
All straight edges together must form the square’s borders (top and two sides), while the only circular arc in the set must appear exactly once along the border or inside.
2) Eliminate by the arc and corner fits.
(C) and (D) place the quarter–circle at locations where the adjoining straight edges would require a second curved piece to close the corner; the given set has only one curved edge \(⇒\) impossible.
(B) requires a long convex curve along a border that exceeds the length of the available curved piece; also the inner diagonals demand a triangle orientation that leaves a gap.
3) Verify (A).
In (A) the quarter–disc sits neatly at the top-left corner; the long straight edge of the trapezium completes the top boundary; the two triangles tile the remaining diagonal region without overlap, their legs matching the square’s side and the long diagonal. No gaps or extra curves are needed.
Therefore the only arrangement possible with all the given pieces is \(\boxed{(A)}\).
