This analogy focuses on the relationship between an individual member and the larger organized group or branch of military service they belong to. In the first pair, Soldier : Army, a soldier is a member of the army, which is the land-based military force of a nation. Applying this same relationship, we need to identify the collective body to which a sailor belongs.
A sailor is a person who works on a ship or is involved in sailing, particularly as a member of a naval force. Therefore, the correct completion of the analogy is Sailor : Navy. The Navy is the branch of a nation's armed forces that conducts military operations at sea.
Let's examine the other options:
- A: Ship is the vessel a sailor works on, not the organization they belong to.
- C: Sea is the environment where the Navy operates, not the organization itself.
- D: Captain is a rank within the Navy, not the collective group.
The analogy correctly links the individual to their specific military branch.
