The stress-strain curve for hot worked metal which has undergone dynamic recovery with increasing strain is _______

The stress-strain curve for hot worked metal which has undergone dynamic recovery with increasing strain is _______ Correct Answer A

In dynamic recovery, the strain hardening after certain point becomes zero and material can be extended for prolonged period without causing increase in required stress.
