Hooke’s law: a law stating that the strain in a solid is proportional to the applied stress within the elastic limit of that solid.
In the OA line Hooke’s law is valid because stress is directly proportional to strain.

Option D is correct friend.. Because, this graph is applicable for the Hooke's law as it has been explained by the scientist Hooke. This law states that "Stress is directly proportinal to the Strain".
Stress ∝ Strain.
It means that if Stress increases, Strain also yet increases.
From the graph, the region between 'O' to 'A', the curve is linear, as it obey the Hooke's law.

Because in OA portion Hook's law is valid.
stress is directly proportional to strain.
