BOnly when turning into a driveway
CWhen traffic conditions make it necessary Correct

A single solid white line discourages lane changes but does not forbid them, so you may cross it when traffic conditions call for it, such as to get around an obstruction. Crossing it is not limited to driveways or U-turns.
