Explanation: Aircraft Very High Frequency (VHF) communications for voice traffic operate primarily within the 118.000 MHz to 136.975 MHz range. This segment is internationally allocated to the Aeronautical Mobile (R) service and is often called the "airband." It facilitates line-of-sight communication between aircraft and air traffic control towers, ground stations, and other aircraft. The extension up to 151.975 MHz in some regions accounts for specific aeronautical allocations, but the core voice communication band is firmly within 118-137 MHz. Option B (108.00 MHz to 117.95 MHz) is incorrect because this range is dedicated to VHF navigation aids like VOR (VHF Omnidirectional Range) and ILS (Instrument Landing System) localizer beacons, not voice communication. Option C (329.15 MHz to 335.00 MHz) is also incorrect; this is the UHF band used for ILS glideslope signals, another navigation aid. Option D (2.000 MHz to 29.999 MHz) describes the High Frequency (HF) band, which aircraft use for long-range communication over thousands of miles, but it is not a VHF range.
