Explanation: Very-high-frequency Omnidirectional Range (VOR) stations, as their name suggests, operate in the Very-high-frequency (VHF) portion of the radio spectrum. The VHF band is generally defined as 30 to 300 MHz. The correct frequency range for VOR stations used in aircraft navigation is from 108.00 MHz to 117.95 MHz. This range falls squarely within the VHF band and is specifically allocated internationally for aeronautical navigation services. Options A and C are incorrect because they list frequencies in kilohertz (kHz). Kilohertz frequencies fall into the Medium Frequency (MF) or High Frequency (HF) bands, not the Very-high-frequency (VHF) band. Option B lists frequencies in MHz, but these are in the Ultra-High Frequency (UHF) band and are primarily used by other navigation systems like the Instrument Landing System (ILS) Glide Slope, not VOR.
