One quarter of the figure below is missing. Which option completes the figure?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
The figure is symmetric about the vertical line through its centre: the right half is the mirror image of the left half. So the missing bottom-right quarter is the mirror image of the bottom-left quarter across the vertical line.
Why the other options are incorrect
Option (1) — Incorrect. This is the correct piece turned through 180°.
Option (2) — Incorrect. This copies the bottom-left quarter as it is; the gap needs its mirror image across the vertical line.
Option (3) — Incorrect. The dot of the correct piece is missing.
