Option 4 : Neither 1 nor 2

Concept:

Piezoelectric material:

The piezoelectric material is the one that possesses the property to convert mechanical energy into electric energy and vice versa.
A commonly known piezoelectric material is quartz.
The mechanism involves the development of electric charge due to the movement of electrons upon application of stress.
Piezoelectric materials have a low value of dielectric constant.

Ferroelectric material:

Ferroelectric materials are materials that exhibit Ferroelectricity.
Ferro electricity is the ability of the material to have a spontaneous electric polarization.
All the ferroelectric materials exhibit a piezoelectric effect due to a lack of symmetry.
