Show answer and solution

Correct option: A

Solution

AM broadcast uses medium frequencies (540–1600 kHz → II), FM broadcast uses 88–108 MHz band → I, Television uses a wide VHF/UHF range of 54–890 MHz → IV, and Satellite communication operates in the GHz microwave range (3.7–4.2 GHz → III). This gives A-II, B-I, C-IV, D-III.
