C)Will have at least the low beam light on.Correct
# Explanation
When a driver uses the additional lane (acceleration or deceleration lane), they must keep the low beam lights on at minimum to improve their visibility to other vehicles. This safety measure is mandatory regardless of light conditions, as it clearly indicates the presence of the vehicle in that maneuvering area. There is no specific speed restriction or obligation to leave the road immediately in an additional lane.
