Select the figure from among the given options that can replace the question mark (?) in the following series.
[Image showing a sequence of four blocks where a central geometric shape rotates clockwise by 45
∘
at each step, and an external dot moves along the corners in a counter-clockwise direction]
- AFigure showing 180
∘
rotation with dot on bottom-left. - BFigure showing the central shape rotated by a cumulative 180
∘
(45
∘
×4 steps) from the start and the dot at its next correct position. - CFigure with incorrect dot positioning.
- DFigure with wrong central element rotation.
Solution & Step-by-step Explanation
By analyzing the pattern steps:
The central figure rotates clockwise by 45
∘
in each successive block. Moving from step 4 to step 5 requires another 45
∘
clockwise rotation.
The outer black dot transitions counter-clockwise from corner to corner at each progressive interval.
Combining both rules brings us precisely to the configuration represented in Option B.
