At mid-day, what would be the best choice in attempting to communicate with a shore station 15 miles distant?

Correct Answer: Option A — VHF-FM

VHF-FM operates via line-of-sight propagation, which is highly reliable for short-range communications regardless of time of day or ionospheric conditions. MF/HF bands (16, 12, 22 MHz) rely on skywave propagation, which is subject to significant diurnal variations and skip-zone effects, making them unsuitable for reliable 15-mile communication.
