In each of the following questions, select a figure from amongst the four…

Concept: In a pattern/figure-completion question, figure (X) is built from continuous decorative bands — an outer woven circular ring and a central diamond lattice — arranged with mirror symmetry about the vertical axis. The missing piece must be the option that lets every band continue as one unbroken, correctly oriented line, so the completed figure stays symmetric and continuous.

Application:

1. The visible top-left and top-right quadrants of figure (X) are mirror images of each other about the vertical axis — each shows an outward corner loop plus a matching arc of the outer circle and arm of the central diamond lattice.

2. The visible bottom-right quadrant continues this same weave, so by the mirror symmetry, the missing bottom-left quadrant must be the mirror counterpart of the bottom-right quadrant.

3. That means the correct piece needs: a corner loop that closes the outer circular band, a diagonal double-line band that lines up with the ring already drawn, and a diamond-lattice arm that continues unbroken into the centre.

4. Figure (1) supplies exactly this — its corner loop closes the outer ring into one continuous band, and its diagonal band and diamond arm continue the lattice without a break.

Cross-check: Mentally placing figure (1) into the blank reproduces a single unbroken circular band and an unbroken diamond lattice at the centre, matching the fully symmetric knot design formed by the rest of figure (X) — with no stray line ends or duplicated strokes at the join. Placing any of the other three figures leaves a visible gap or seam in the ring or lattice.

Hence, the figure that completes the pattern is figure (1).
