Step 1: Observe sequence.
The coloured circles (orange, green, yellow, blue) rotate in a cyclic order across frames. The centre always remains white.
Step 2: Track movement.
In each step, the four coloured circles shift clockwise around the square.
Step 3: Apply to missing case.
Before missing frame:
- Orange is at bottom-right,
- Yellow at top-left,
- Green at right,
- Blue at bottom.
After rotation:
- Orange → top-right,
- Yellow → bottom-left,
- Green → bottom-right,
- Blue → left.
Step 4: Compare with options.
Option (C) matches this rotation correctly.
Final Answer:
\[
\boxed{\text{C}}
\]
