Answer:
The correct answer is option (a) electron beam machining.
Explanation:
Electron beam machining (EBM) exists a thermal machining method in which high-velocity electrons concentrated into a narrow beam are utilized for instantly heating, melting, or vaporizing the material. This method exists utilized in many applications, including drilling, cutting, annealing, and welding.
Therefore, the correct answer is option (a) electron beam machining.
