Choose the figure that comes next in the given figure series.

CONCEPT: In a figure series, the same small set of shape-types repeats in every panel; the rule to find is which single attribute (fill state, position, count, or rotation) changes on a fixed repeating cycle while everything else stays constant, then apply that same cycle to predict the missing panel.

APPLICATION: Every panel in this series contains exactly three shapes drawn from the same set - a square, a circle, and a star. Tracking only the star's fill state across the five panels: panel 1's star is unfilled (outline only), panel 2's star is solid/filled, panel 3's star is unfilled again, and panel 4's star is solid/filled again - an alternating cycle of length 2 (odd panels unfilled, even panels filled), while the square and circle stay outline-only in every panel throughout.

CROSS-CHECK: Panel 5 is an odd-numbered panel immediately after the filled star of panel 4, so by the same alternating rule it must revert to the unfilled step: all three shapes - square, circle, and star - drawn in outline only, with no shape shaded solid. Checking each candidate figure against this rule (right shape set AND no filled shape) singles out exactly one figure that keeps every shape unshaded.
