The network element and V—L characteristics are shown in fig. (a) and (b). The element is—

1. Non-linear, active and bilateral
2. Linear, passive and bilateral.
3. Non-linear, passive and non-bilateral
4. Non-linear, active and non-bilateral.

Correct Option: D

The given figure is non-linear because after 1 volt the output becomes constant.
Any element will be passive if the ratio V/I is positive any time, so the given output shown that the element in Passive.
Element will be bilateral if and only if the magnitude (i.e. V, or I) is same in both the direction. Here the given element is non-bilateral.
