The correct answer is D) All of the above. This is because, as per the rules of the road for the Western Rivers, a power-driven vessel crossing a river must keep out of the way of a sail vessel descending the river, a power-driven vessel ascending the river, and a vessel restricted in its ability to maneuver crossing the river. These are all vessels with the right-of-way, and the power-driven vessel crossing the river must take early and substantial action to keep clear of them. The other options are incorrect because they only mention one type of vessel, whereas the rules require the power-driven vessel to give way to all three types of vessels in the situation described.
