The correct answer is C) The wind comes from broad on the bow to the quarter while underway. Reaching is a sailing term that describes a point of sail where the wind is coming from a direction between the bow and the beam (side) of the sailboat. This allows the sailboat to sail at an angle to the wind, taking advantage of the lift generated by the sails. Reaching is considered an efficient point of sail, as the boat can make good progress while the wind is not directly on the bow or the stern. The other options are incorrect because A) describes a situation where the wind has no effect on the vessel, which is not reaching, and B) and D) describe wind directions that are not considered reaching (directly on the bow or stern).
