Select the option that fits in the place of the question mark to complete the pattern.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) →
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-left quarter is the mirror image of the bottom-right quarter across the vertical line.
Why the other options are incorrect
Option (1) — Incorrect. This copies the bottom-right quarter as it is; the gap needs its mirror image across the vertical line.
Option (3) — Incorrect. This is the correct piece turned through 90° clockwise.
Option (4) — Incorrect. The black triangle of the correct piece is missing.
