The correct answer is "form". A shape that has volume or appears to have a three-dimensional (3D) quality is called a form. To determine the answer, you can use your knowledge of basic geometric concepts. In this case, you need to identify the term that describes a shape with volume or 3D characteristics. Option "space" refers to the area or expanse that an object occupies, but it doesn't specifically describe a shape's 3D quality. "Line" is a one-dimensional shape, meaning it only has length but lacks width or depth. "Square" is a two-dimensional shape, meaning it has both length and width but lacks depth. Therefore, the correct answer is "form".
