Final answer:
In a crossing situation, the give-way vessel turns to starboard and passes astern the stand-on vessel. Hence the correct answer is option D
Step-by-step explanation:
In a crossing situation, the give-way vessel turns to starboard and passes astern the stand-on vessel. This is known as the proper procedure for a vessel to take when faced with a crossing situation. By turning to starboard and passing astern, the give-way vessel ensures that it avoids a collision and gives the stand-on vessel the right of way.
Hence the correct answer is option D
