Which of the following represents the administrative support branch in the Navy?

The administrative support branch in the Navy is primarily represented by the N1 division. This branch is responsible for personnel management, which includes areas such as manpower, personnel administration, and the management of sailor assignments. Essentially, N1 focuses on ensuring that the right personnel are in the right places within the Navy, handling issues like promotions, evaluations, and retention.

In contrast, the other divisions have distinct roles that do not pertain to administration. N2 focuses on intelligence matters, N3 is responsible for operations and training, and N4 oversees logistics, including supply chain management and transportation. Each of these divisions plays a critical role within naval operations, but N1 specifically addresses the administrative and personnel functions, making it the correct answer for the given question.
