Step-by-step solution
(A) A Klystron valve or the magnetron valve are generally used for the production of electromagnetic waves and that electromagnetic wave is Microwave. So, A → I V . (B) Gamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles.So, B → I (C) Radio waves can be produced by rapid acceleration and deceleration of electrons in aerials (conductors). These can be detected by receivers of aerials. So, C → I I (D) X-rays are produced when a
