The choice that states a portable VHF radio can be operated ashore is partly accurate. Specifically, while listening to maritime VHF channels can be conducted from land without any legal issues or licensing requirements, transmitting from ashore is generally not permitted unless specific conditions are met.
In many regulatory environments, the use of VHF radios is intended primarily for maritime communication. When ashore, individuals typically do not hold the rights to transmit messages unless they have the appropriate licenses or permissions. Therefore, using such a device solely for receiving communications is acceptable without running afoul of regulations.
With this understanding, while listening is allowed, transmitting is restricted. The other choices indicate various degrees of prohibition or restriction, which do not accurately convey the nuances concerning the operation of VHF radios from land.
