Which statement is a disadvantage related to frequency usage?

• A. Number of frequencies limited
• B. Jamming
• C. Atmospheric conditions
• D. Interception of signals

Answer: (A)

The main concept here is that the radio frequency spectrum is finite, so only a limited number of distinct frequencies can be used simultaneously in a given area or band. As many users and services compete for access, regulators must allocate frequencies, set guard bands, and license operations to prevent interference. This scarcity of available frequencies is the fundamental disadvantage of frequency usage because it constrains how many channels can operate at once and drives the need for careful planning and coordination. Jamming is a interference threat that can affect communications on any frequency, but it isn’t a inherent drawback of frequency usage itself. Atmospheric conditions influence how signals propagate and can affect reliability, yet they don’t describe the limitation of how many frequencies are available. Interception of signals concerns security and privacy rather than the basic scarcity of the spectrum.
