Explanation: Maritime VHF operations are specifically allocated to the 156-164 MHz frequency range. This falls within the Very High Frequency (VHF) band, known for its line-of-sight propagation characteristics. This makes VHF ideal for reliable, short to medium-range communication essential for maritime safety, navigation, and general ship-to-ship or ship-to-shore communications. Standardized international channels within this band ensure interoperability between vessels, port authorities, and rescue services globally. Option A, 3-30 MHz, describes the High Frequency (HF) band, which is used for long-range maritime communication via skywave propagation, not "VHF." Option B, 88-108 MHz, is the commercial FM broadcast radio band. Option D, 540-1640 kHz, is the AM broadcast band (Medium Wave). These other bands serve different purposes with distinct propagation characteristics unrelated to Maritime VHF.
