Show answer and explanation

Correct answer: (C) Ultrasonic machining

Explanation

Ultrasonic machining drives abrasive particles with high-frequency mechanical vibration, causing erosion and microfracture. The other processes principally use electrical/thermal energy to remove material. Therefore C matches the requested mechanical-energy category.
