What is the main feature of a closed shape?
Answer and explanation
Correct answer: Its boundary is complete
The correct answer is B, a complete boundary. A closed shape is formed when its outline or boundary connects continuously so that there is no gap between the beginning and the end. Because the boundary is complete, it encloses an inside area that can be recognized, filled with colour, shaded, or used in a design. A circle, triangle, rectangle, and square are all closed shapes when their outlines are fully joined. Option A describes an open shape, whose boundary has a break. Options C and D concern unrelated ideas: visibility and sound are not defining properties of a closed visual shape. The essential test is simple: trace the outline and check whether it returns to the starting point without interruption. Therefore B is correct.
