The correct answer highlights a crucial aspect of maritime safety. Coast Guard assistance is required when the crew is in immediate danger, as the primary goal of emergency services is to protect life. If a vessel is aground, the presence of danger to the crew can stem from various factors, such as adverse weather, flooding, or the potential for capsizing. In such situations, the Coast Guard prioritizes the safety of individuals on board, and swift assistance is necessary to ensure that no one is harmed.

The other options involve conditions that may relate to the status of the vessel but do not inherently necessitate immediate assistance from the Coast Guard. For instance, the impossibility of reaching a shoreline may indicate a troublesome situation, but it does not automatically result in an emergency. Being within close proximity to shore does not imply that the vessel requires assistance unless there are safety concerns. Similarly, the rising tide might provide a future possibility for the vessel to float free, which does not directly correlate with an immediate need for help. Understanding these distinctions is vital in determining when to seek Coast Guard assistance effectively.
