Choose the appropriate figure from the choices given in image image_b9b8db.png to replace the question mark (?) in the matrix.

By analyzing the matrix of blue figures shown in image_b9b8db.png, we can observe a clear additive pattern across the columns for each row:
* Row 1:
* Column 1 shows a circle containing an upright triangle with a central dot.
* Column 2 shows a circle containing an inverted triangle with a central dot.
* Column 3 combines the internal geometric features of Column 1 and Column 2, resulting in a circle containing a Star of David (the superposition of the upright and inverted triangles) with a central dot.

* Row 3 follows the identical combination rule:
* Column 1 features an outer circle enclosing an upright triangle, which further encloses an inner circle with a central dot.
* Column 2 features an outer circle enclosing an inverted triangle, which further encloses an inner circle with a central dot.
* Column 3 must combine these components: an outer circle enclosing a Star of David, which then encloses the inner circle with a central dot.

This structural combination corresponds perfectly to the blue illustration in Option C.
