Solution

The correct option is D 1, 2 and 3

Explanation:

All statements are correct

  • The radio frequency spectrum (which is simply referred to as spectrum) is only a comparatively small part of the electromagnetic spectrum, covering the range from 30 Hz to 300 GHz.
  • Lower frequencies have less bandwidth capacity than higher frequencies. It means that signals that carry a lot of information (such as television, broadband, or mobile phones) are better placed in the higher frequency bands while simple radio (audio) signals can be carried by the low-frequency waves.
  • Spectrum has been internationally accepted as a scarce, finite, and renewable natural resource that is susceptible to degradation in case of inefficient utilization
