Find the next figure in the series.

Let's track the position shifts of the four shapes (Star $★$, Circle $\bullet$, Rectangle/Square $■$, Triangle $▼/▲$) located at the four corners inside the main square frame:
1. Box 1 Positions:
* Top-Left: Star ($★$)
* Top-Right: Circle ($\bullet$)
* Bottom-Left: Rectangle ($■$)
* Bottom-Right: Upward Triangle ($▲$)

2. Box 2 Positions:
* Top-Left: Rectangle ($■$)
* Top-Right: Star ($★$)
* Bottom-Left: Rightward Triangle ($\text{black}forward$)
* Bottom-Right: Circle ($\bullet$)
Observation: The shapes are moving in a clockwise cycle across the corners. The triangle is also changing its orientation pointing direction at each step.

3. Box 3 Positions:
* Top-Left: Inverted Triangle ($▼$)
* Top-Right: Rectangle ($■$)
* Bottom-Left: Circle ($\bullet$)
* Bottom-Right: Star ($★$)

4. Box 4 (Missing Piece):
Shifting the positions from Box 3 clockwise by one corner:
* The Circle ($\bullet$) moves from Bottom-Left to Top-Left.
* The Inverted Triangle moves from Top-Left to Top-Right (and updates its point direction to leftward $\text{black}backward$ or upward).
* The Rectangle ($■$) moves from Top-Right to Bottom-Right.
* The Star ($★$) moves from Bottom-Right to Bottom-Left.

Looking at the options, option (D) perfectly matches this distribution:

* Top-Left: Circle
* Top-Right: Left-pointing triangle
* Bottom-Left: Star
* Bottom-Right: Rectangle
