The following curve represents the relation between the normalized creep rate with normalized stress. In which of the the region, the Harper-Dorn Creep law is valid? Correct Answer I

The Harper-Dorn creep law is valid at lower stress range with lower acceptable temperature limit, so the first region indicates the region where the Harper-Dorn law is correct.
