2. A-IV, B-III, C-I, D-II
3. A-IV, B-III, C-II, D-I
4. A-I, B-II, C-IV, D-III

Correct answer: A-IV, B-III, C-II, D-I

Solution

The correct option matches each signal type with its appropriate frequency range: television signals typically operate around 6 MHz, radio signals around 2 MHz, high-quality music can be transmitted up to 20 kHz, and human speech generally falls within the 3 kHz range.
