Choose the option which completes the given figure series.

By observing the movement and rotation of elements across successive blocks in the figure series:Trace the rotation or shift of the main outer symbol/line configuration.Track the inner shaded elements or geometric shapes which typically rotate clockwise or counterclockwise by $45^{\circ }$ or $90^{\circ }$, or shift positions diagonally.Matching these systematic transformations leads uniquely to the pattern presented in Option A.
