Question 106Navigation General

The correct answer is C) Coast Guard. The U.S. Coast Guard is the federal agency responsible for maintaining and operating the system of federal aids to navigation in the United States. This includes lighthouses, buoys, beacons, and other markers that help mariners navigate safely. This responsibility is outlined in federal law and regulations under the Coast Guard's authority. The other answer choices are incorrect because the National Ocean Service, Maritime Administration, and Corps of Engineers do not have the primary responsibility for federal aids to navigation, which is the domain of the U.S. Coast Guard.
