Which of the following frequency ranges falls within the VHF classification?

The VHF (Very High Frequency) classification is defined by the frequency range of 30 MHz to 300 MHz. This classification is widely used in various applications, such as television broadcasting, two-way radio communication, and FM radio.

The correct choice identifies a range that aligns perfectly with the VHF classification, specifically falling between 30 MHz and 300 MHz.

In contrast, the other options describe frequency ranges that do not accurately fall within the VHF spectrum. The first option covers frequencies from 10 kHz to 100 GHz, which encompasses many different bands, including VLF, LF, MF, HF, VHF, UHF, and beyond, thus being too broad. The second option spans from 300 to 3000 KHz, which is much lower than VHF, corresponding to the medium frequency (MF) range instead. Lastly, the fourth option includes frequencies from 3 to 30 MHz, which aligns with the high frequency (HF) range of the electromagnetic spectrum. Therefore, the choice correctly identifying the VHF range is the one that specifies frequencies between 30 MHz and 300 MHz.
