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

Correct answer

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

Step-by-step solution

AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. AM Broadcast range →   540 – 1600   kHz   FM broadcasting is the method of radio broadcasting that uses frequency modulation (FM). FM Broadcast range → 88   –   108   MHz Television → 54   –   890   MHz Satellite communication → 3 . 7 – 4 . 2   GHz ∴ A-II, B-I, C-IV, D-III
