Best answer
The correct choice is (a) True

Best explanation: In electron beam melting technology, the vacuum chamber is used which requires maintenance time to time and a shield is also used during the process which covers the x-rays produced by the electron beam in the process. These all expensive equipment are used which makes this technology very costly.
