How will cross-contour lines change across a folded sheet of paper?

Answer and explanation

Correct answer: They bend according to the folds and surface direction

Cross-contour lines describe how a surface turns across its form, rather than merely tracing its outer boundary. On a folded sheet, the surface direction changes at each crease, so the lines must bend, change spacing, or alter direction to follow those planes. Option B is correct. They are not required to remain straight everywhere, occur only at edges, or disappear simply because a region is in shadow.
