Options

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

Correct answer

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

Step-by-step solution

Matching electromagnetic wave sources: Radio-wave (A) - produced by rapid acceleration of electrons in antennas and transmitters, matches IV. Micro-wave (B) - produced by Magnetron valve, matches I. Infrared-wave (C) - due to change in vibrational modes of atoms and molecules, matches II. X-ray (D) - due to inner shell electrons moving from higher to lower energy levels, matches III. Correct pairing: A-IV, B-I, C-II, D-III
