D Correct answer
Explanation

(A) Ultrasonic Machining (UCM) is a mechanical metal removing process for brittle material by using high frequency oscillations of shaped tool using abrasive slurry. (B) Electro Chemical Machining (ECM) uses electrical current to remove the metal relies on the principle of electrolysis for material removal. (C) Abrasive water jet machining is a process that uses a very high speed water jet mixed with abrasives to cut any type of matarial. (D) Laser beam machining utiliser the energy from the coherent light beam which first melt and then vaporise the tiny metal particles, in which thermal energy is used.
