Which of the option figures completes the given pattern?

Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
The figure is symmetric about both the vertical and the horizontal lines through its centre: each quarter is the mirror image of the quarter beside it. So the missing top-left quarter is the mirror image of the top-right quarter across the vertical line.

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. The dot of the correct piece is missing.
Option (4) — Incorrect. One line of the correct piece is missing.
