The correct answer is C) complete the stroke, raise your oar slightly, swing it forward, and place it in the boat. When the steersman gives the command "Way enough", it means that the forward motion of the lifeboat should be stopped. To accomplish this, the rowers should complete their current stroke, raise their oars slightly out of the water, swing them forward, and place them in the boat. This maneuver allows the boat to gradually lose momentum without abruptly stopping, which could cause the boat to become unstable. The other options are incorrect because A) lifting the oar to a vertical position would not effectively stop the boat's forward motion, B) leaving the oar blade in the water would create unnecessary drag, and D) holding the oar out from the boat and level with the water would not effectively stop the boat's movement.
