Find the next figure in the given series:

Let's analyze the pattern across the figures in the series:
1. Alternation of Shapes and Symbols: * The outer main shape alternates between a Square and a Triangle (Square $\to$ Triangle $\to$ Square $\to$ ?). Thus, the fourth figure must be a Triangle.
* The inner white symbol alternates between a Star and a Circle (Star $\to$ Circle $\to$ Star $\to$ ?). Thus, the fourth figure must contain a Circle.

2. Rotation Pattern:
* Comparing Figure 1 and Figure 3 (the squares), Figure 3 is obtained by rotating Figure 1 by $180^{\circ }$. The square looks identical, but the white star moves from the bottom-left corner to the top-right corner.
* Following the same logic, Figure 4 must be obtained by rotating Figure 2 (the triangle) by $180^{\circ }$.
* Rotating the upward-pointing triangle by $180^{\circ }$ makes it a downward-pointing triangle.
* The white circle at the bottom-left corner will move to the top-right corner.

This perfectly matches the configuration shown in Option C.
