The series shows a square divided into 8 triangular sectors with a shaded pattern moving clockwise:



From the options given below, choose the option that represents the figure most suitable to continue the pattern given above.

The shaded pattern moves step-by-step in a clockwise direction around the center of the grid, while gradually expanding the total area covered (from a single sector to two adjacent sectors forming a small square or larger triangular block). This systematic clockwise advancement determines the subsequent state of the sequence.
