The correct answer is B) inshore stern line. This is the correct answer because the line labeled "B" in the illustration is connected to the stern (rear) of the vessel and is on the inshore (closer to land) side. The "inshore stern line" is used to secure the stern of the vessel to the dock or mooring on the side of the vessel that is closest to land. The other answer choices are incorrect because they do not accurately describe the line labeled "B" in the illustration. The "after breast line" (A) and "after spring line" (C) are not connected to the stern, and the "offshore stern line" (D) would be on the side of the vessel that is farther from land.
