Question from UPPSC Prelims CSAT 2025

Explanation:

In a parallelogram, adjacent angles are supplementary and opposite angles are equal. If one angle is 90°, then all angles become 90°, making it a rectangle. If all sides are equal, the parallelogram is a rhombus.

A quadrilateral that is both a rectangle (all angles 90°) and a rhombus (all sides equal) is a square. Therefore, the figure described is a square.
