Concept:The series follows a pattern of 90° clockwise rotation of curved arcs in each step.
Explanation:First figure has arcs in a vertical orientation.
Second figure: arcs rotate 90° clockwise, becoming horizontal.
Third figure: arcs rotate another 90° clockwise, vertical again but with reversed direction.
Next figure must continue the rotation by another 90° clockwise.
This makes the arcs horizontal, now facing downward.
The only option with horizontal arcs facing downward is option B.
Answer:B
