Poisson's ratio: It is a measure of the ratio of lateral strain to axial strain. The typical range of Poisson's ratio is between 0.15 and 0.25. Suggests that when a material is stretched, it tends to contract laterally. This behavior is typically for metals, where the material experiences some degree of contraction perpendicular to the applied force.

Here, option 2 is correct.
