Diagram for USCG Navigation General: You are inbound in a channel marked by a range. The range line is 216° T. You...
A Continue on the present heading until the range is in line then alter course to the right.
B Immediately alter course to 216° T if the range is closing.
C Immediately alter course to the right to bring the range in line.
D Immediately alter course to the left to bring the range in line.
AI Explanation

The correct answer is C) Immediately alter course to the right to bring the range in line. When navigating a channel marked by a range, you want to keep the range line in alignment with your course. Since you are steering 213° T and the range line is 216° T, you need to immediately alter course to the right to bring the range in line at 216° T. This will ensure you remain on the proper course through the channel. The other options are incorrect because continuing on your current heading (213° T) would cause you to drift off the range line, and altering to the left would take you further off the range line.
