We observe the transformation between the given three figures:
- In each step, the shape rotates 90° clockwise.
- The position of the dot also rotates clockwise across corners.
- The arrow’s direction rotates too, matching the shape’s orientation.
From figure 1 to 3, this consistent pattern is followed.
Hence, figure 4 must follow the same 90° clockwise rotation of both the shape and its internal arrow, and the dot moves to the next corner.
Among the answer figures, only option (b) continues all these changes accurately.
