Solution

UHF stands for ultra high frequency and VHF is the abbreviation of very high-frequency signals.
These are used in radio communication.
Space wave propagation occurs in UHF and VHF band.
These waves travel through the atmosphere and are not reflected by the ionosphere.
Thus, we can say that they are limited to line of sight.
Thus,
Option B) both Assertion and Reason statements are correct but the Reason statement is not the correct explanation for Assertion is the correct option.
