Which of the following constitutes a proper salutation in naval correspondence?

In naval correspondence, the proper salutation is formal and should include the rank and last name of the individual being addressed. This demonstrates respect and adheres to the established protocol within military communication. The format "Dear [Rank] [Last Name]" is specifically designed to maintain a level of professionalism and formality that is expected in military settings.

Using a recipient's rank ensures that the respect accorded to their position is appropriately reflected in the communication. This personalized salutation is essential in fostering clear and respectful dialogue within the Navy.

The other options, while they might be acceptable in general correspondence, do not meet the specific requirements for naval correspondence. "Dear Sir or Madam" lacks personalization and does not acknowledge the specific rank of the recipient. "To Whom It May Concern" is too vague and impersonal for the intended communication in military contexts. "Attention" by itself does not serve as a salutation and lacks the necessary formal structure needed in naval correspondence.
