The correct frequency limits of the VHF (Very High Frequency) spectrum are indeed from 30 to 300 MHz. This range is significant in amateur radio, television broadcasting, and various communication services.

VHF frequencies are notable for their propagation characteristics, including line-of-sight communication and the ability to penetrate atmospheric conditions better than higher frequency bands. This is why amateur radio operators and other users often utilize VHF frequencies for local communications and emergency services.

The other ranges provided either fall into different categories of radio frequencies or extend beyond VHF. For instance, the 3 to 30 MHz range falls under the HF (High Frequency) spectrum, which is known for long-distance communications, while the 300 to 3000 MHz range pertains to the UHF (Ultra High Frequency) spectrum, typically used for television broadcasting and mobile communications. Therefore, the VHF spectrum specifically encompasses the range indicated in the correct answer.
