What is the VHF frequency range?

Explanation:
VHF covers roughly 30 to 300 megahertz, which corresponds to wavelengths about 10 to 1 meters. This range is used for line-of-sight communications—signals travel between transmitters and receivers by direct paths rather than relying on long-distance ionospheric reflection. The other options fall outside this band: frequencies below 30 MHz are in the HF/shortwave range, while frequencies above 300 MHz belong to UHF and higher. So the VHF range is defined as 30–300 MHz.
