The given sequence consists of a series of figures that display a pattern based on the rotation and placement of symbols within a circle. Each circle is divided by a cross, and symbols are placed in each quadrant.

Examining the sequence:

• In Figure I: The circle contains a minus sign (-), a plus sign (+), a circle (○), and a triangle (△).
• In Figure II: The symbols have rotated clockwise. The minus sign moves to the left quadrant, the plus sign to the bottom, the circle to the right, and the triangle to the top.
• In Figure III: The symbols continue rotating clockwise following the same pattern.

This pattern indicates that with each step, every symbol rotates one position clockwise.

Based on this analysis, the arrangement of symbols in Figure IV should continue the pattern:

• Minus sign (-) will move to the upper quadrant.
• Plus sign (+) will move to the right quadrant.
• Circle (○) will move to the bottom quadrant.
• Triangle (△) will move to the left quadrant.

From the given options, the correct choice for the next figure in the sequence is:

This option shows the symbols rotated in the correct order, continuing the pattern established by the sequence.
