Answer: Option C

Solution(By Examveda Team)

Stress relaxation is a gradual reduction in stress with time at constant strain.
Stress relaxation occurs in polymers when they are held in a strained state for long periods of time.
These alloys have very good resistance to stress relaxation and are therefore used as spring materials.
