To determine the distance from the lighthouse to the ship, you would typically use the information provided in conjunction with concepts such as the positions of these entities and potentially any geometric relationships (e.g., right triangles if applicable). However, the options you've provided seem to imply a specific scenario or problem that might clarify the distances in question.
From the statements provided, the correct statement about the distances between the entities (lighthouse, coastguard, and ship) should address which distance is the longest and which is the shortest.
In terms of the options you've shared, if we assume that the distance from the coastguard to the ship must be the shortest distance, that implies the ship is closer to the coastguard than to the lighthouse.
Please let me know if there's further specific context or information surrounding this question. For now, without additional context, the need to specify an exact distance remains unclear.
