Correct Answer:
B. French curves
Explanation:
A flexible curve, often referred to as an adjustable or flexi curve, is a specialized drafting tool featuring a bendable core, typically made of lead or metal, encased in a protective rubber or plastic coating. This design allows the tool to be shaped by hand to match any series of plotted points, maintaining that specific contour so a smooth, continuous line can be drawn. Unlike French curves, which have fixed shapes, the flexible curve is adjustable and versatile, making it ideal for creating custom or complex non-circular curves in engineering, tailoring, and graphic design.
