Which of the following will complete the adjoining figure

The correct answer is Option 1:

The large square is divided into four smaller squares, and each small square contains curved arcs that meet smoothly at the boundaries.

Three parts are already filled; the bottom-left square is missing.

Pattern rules

1. The curves continue smoothly across the borders of adjacent squares.

2. The arc endpoints from the neighboring squares must connect in the missing square.

3. The small circle with a line also continues in the same orientation.

   Option 1: The arcs align perfectly with the curves coming from the top-left and bottom-right squares, and the small circle with the line is placed consistently.
