\nThe correct answer is A. Hooke’s law states that the stress is directly proportional to the strain within the elastic limit of a material. More specifically, this linear relationship holds true only in the initial part of the elastic region, which is known as the proportional region. Beyond the proportional limit, the material may still behave elastically (return to its original shape upon unloading), but the stress-strain relationship becomes non-linear.

\nHooke’s law (Stress \u221d Strain) is strictly valid only in the proportional region of the stress-strain curve.

\nThe stress-strain curve for a ductile material typically shows several regions: proportional limit, elastic limit, yield point, ultimate tensile strength, and fracture point. The elastic limit is the maximum stress a material can withstand without permanent deformation. The proportional limit is the point up to which stress is directly proportional to strain. For many materials, these two points are very close, but Hooke’s law is defined by the proportionality.
