Which of the option figures completes the given pattern?

Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
The figure looks the same after a half turn about its centre: each quarter is the opposite quarter turned through 180°. So the missing top-left quarter is the bottom-right quarter turned through 180°.

Why the other options are incorrect
Option (1) — Incorrect. This copies the bottom-right quarter as it is; the gap needs that quarter turned through 180°.
Option (2) — Incorrect. This is the correct piece turned through 90° anticlockwise.
Option (3) — Incorrect. The dot of the correct piece is missing.
