The museum has an interesting collection of nautical items, including ocean maps, sails, and anchors.

“Nautical” means relating to ships, sailors, or sailing. The collection includes sails and anchors, which are connected with ships and sailing, so choice D, “of or relating to ships or sailing,” is correct. Choice B refers more specifically to salt water, but that is not the meaning of “nautical.”
