Explanation:

Step1: Recall rotational symmetry definition

A shape has rotational symmetry if it looks the same after a rotation (less than 360°) about a point.

Step2: Analyze option A

The trapezoid in option A does not look the same after any rotation less than 360°.

Step3: Analyze option B

The irregular pentagon in option B does not look the same after any rotation less than 360°.

Step4: Analyze option C

The heart - shaped figure in option C does not look the same after any rotation less than 360°.

Step5: Analyze option D

A square (the shape in option D) has rotational symmetry. It looks the same after a 90°, 180°, and 270° rotation about its center.

Answer:

D. Square - shaped figure (the figure in option D)
