A figure that has rotational symmetry is one that looks the same after a certain rotation.
Among the options provided:
A. Parallelogram - Yes, it has rotational symmetry (180 degrees). B. Irregular pentagon - No, it generally does not have rotational symmetry. C. Trapezoid - No, it typically does not have rotational symmetry. D. Rectangle - Yes, it has rotational symmetry (90 degrees and 180 degrees).
Both the parallelogram and rectangle have rotational symmetry, but if you need one answer specifically, the rectangle is the most common example.
Thus, the figure that has rotational symmetry is: D. rectangle
