  1. AA-I, B-II, C-III, D-IV
  2. BA-IV, B-I, C-II, D-III
  3. CA-I, B-III, C-IV, D-II
  4. DA-IV, B-III, C-II, D-I

Correct answer

B. A-IV, B-I, C-II, D-III

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
