The correct answer is the option a - Mechanical.
Ultrasonic Machining (USM) is a process in which the material of the workpiece is removed by the repetitive impact actions of abrasive particles.
USM is mainly used for machining brittle materials which are usually poor conductors of electricity and thus cannot be processed by Electrochemical and Electro-discharge machining (ECM and ED).
