Which line can suggest roundness on the surface of an object?

Answer and explanation

Correct answer: Cross-contour line

The correct answer is A, cross-contour line. A contour line follows or describes the edge of an object, while a cross-contour line travels across its surface. Its direction changes according to the object’s curvature. For example, curved bands drawn across a ball or a cylinder can make the viewer understand that the surface turns around in three dimensions. The line does not merely mark the outside boundary; it helps describe the surface and volume. B, a straight border, may mark an edge but cannot by itself communicate the rounded surface. C, colour-wheel line is not a standard line type for showing an object’s curvature. D, a paper-fold line indicates a crease and does not generally explain the roundness of a solid object. Memory cue: lines crossing a form and following its bend are cross-contour lines.
