e. None of the above

Solution

Creep is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses. Creep is more severe in materials that are subjected to heat for long periods, and generally increases as they near their melting point. The rate of deformation is a function of the material properties, exposure time, exposure temperature and the applied structural load. Depending on the magnitude of the applied stress and its duration, the deformation may become so large that a component can no longer perform its function.

So creep depends on all of theabove.
