Which option figure will complete the pattern in the question figure? (Rotation is not allowed)

This is a pattern-completion problem: the question figure is a framed design with one portion left blank, and a single option must slot into that gap.
The correct piece has to carry the curves, straight lines and any small marks straight across the join so that the finished design reads as one unbroken whole.
Because rotation is not allowed, the missing piece must fit in precisely the orientation shown, without being turned in any way.
Checking the gap edge by edge, three options fail to meet the surrounding strokes cleanly, leaving a break or a mismatch at the boundary.
Only one option aligns with every edge of the opening and continues the design smoothly; the figure is not reproduced here.
Hence the figure that completes the pattern is the figure shown as option 4.
