Correct answer
BA-IV, B-I, C-II, D-III
Step-by-step explanation
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
