When we say that a material sample has reached its elastic limit, we mean that
A) if any further stress is applied, the sample will break.
B) if any further stress is applied, the deformation of the sample will not be reversible.
C) the deformation no longer follows Hooke's law.
D) the material will continue deforming with no further additional stress.
E) None of the other choices is correct.

When a material sample reaches its elastic limit, it means that it has been subjected to stresses that have caused it to deform, but the deformation can still be reversed by removing the stress. However, if any further stress is applied beyond this limit, the deformation will become permanent and irreversible, leading to plastic deformation or even fracture. Hence, option B is the correct answer as it describes the irreversible nature of the deformation beyond the elastic limit. Options A, C, and D are incorrect as they do not accurately describe the concept of elastic limit.
