The correct answer is D) All of the above. On the Western Rivers, a power-driven vessel bound downstream has the responsibility to initiate maneuvering signals, propose the manner of passage, and has the right of way when meeting an upbound vessel. This is based on the Inland Navigation Rules, which state that the downstream vessel shall propose the manner of passage and shall initiate the maneuvering signals. Additionally, the downstream vessel has the right of way, as it is more difficult for the upbound vessel to maneuver. The other options are incorrect because they do not fully capture the responsibilities and rules governing the downstream vessel in this scenario on the Western Rivers.
