Right answer is (a) True

Easiest explanation: It is True. On applying pressure to piezo-electric crystal, electricity is generated. The piezo electric effect is a property of a natural crystalline substance to develop electric potential along a crystallographic axis in response to the movement of charge as a result of mechanical deformation. Thus, piezo-electricity is pressure electricity.
