Deformation that occurs due to stress over a period of time is known as ____________

A. Wear resistance

B. Fatigue

C. Creep

D. Fracture

This question was posed to me in a national level competition.

This intriguing question comes from Mechanical Properties topic in division Properties of Engineering Materials of Engineering Material & Metallurgy

The correct option is C. Creep

Easiest explanation: Creep is the time-dependent deformation of the material under stress. Wear resistance, fatigue, and fracture deal with deformation under stress without a time factor, i.e. they are time-independent.
