Identify A, B and C in the following stress- strain plot of a polymer.
The given stress-strain graph of a polymer indicates the different regions corresponding to its mechanical behavior under applied stress.
A: Elastic region (where the material undergoes reversible deformation). B: Yield point (where the material transitions from elastic to plastic behavior). C: Plastic region (where permanent deformation occurs).
