Which of the option figures completes the given pattern?

Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
The figure looks the same after a quarter turn about its centre: going clockwise, each quarter is the one before it turned through 90° clockwise. So the missing top-right quarter is the top-left quarter turned through 90° clockwise.

Why the other options are incorrect
Option (2) — Incorrect. This is the correct piece flipped across its middle line (its mirror image).
Option (3) — Incorrect. One line of the correct piece is missing.
Option (4) — Incorrect. The dot of the correct piece is missing.
