Correct option is C
Creep is the tendency of a solid material to slowly move or deform permanently under the influence of mechanical stresses. It occurs over a prolonged period of time when the material is subjected to a constant load or stress, especially at high temperatures. Creep is particularly important in materials that are exposed to high temperatures and stresses, such as in jet engines, turbines, and other components subjected to long-term loads. Unlike brittle or ductile fracture, which occurs relatively quickly, creep is a gradual and progressive deformation process.
