The correct answer highlights a crucial safety feature in vehicles designed to alert other road users. When a vehicle is preparing to back up, its reverse lights illuminate. This is a standard signal indicating that the driver intends to move the vehicle in reverse and serves as a warning to pedestrians and other drivers that the vehicle is about to back up. This visual cue is particularly important in preventing accidents, as it increases awareness of the vehicle's actions.

In contrast, while waving to pedestrians, using turn signals, or honking the horn can indicate various intentions on the road, they do not specifically denote that a vehicle is preparing to reverse. Waving to pedestrians may suggest courteous communication, flashing turn signals can indicate a lane change or a turn, and honking may be used to signal caution or alertness to another driver. However, none of these actions provide the clear, unambiguous indication of reversing that the activation of reverse lights does.
