• A. Polygon
• B. Circle
• C. Line
• D. Shape

Answer: (A)

A closed plane figure with straight sides is called a polygon. The key idea is that a polygon is made up of straight line segments—which are its sides—that connect at endpoints to form a closed shape. This distinguishes it from other figures like circles, which have curved edges, or a single line, which isn’t closed, or a generic term like shape, which isn’t specific about having straight sides and a closed boundary. So, the term that best fits a figure composed of straight segments that enclose a space is polygon.
