How should a driver overtake the cyclist in this situation?

Overtake the cyclist, but without crossing any of the lines.
By sounding the horn to warn the cyclist they intend to pass.
By straddling both lines and keeping close to the cyclist.
By crossing the broken white line.

Explantion: Where there are two lines in the centre of the road, you must obey the one closest to you. So, if the closest line is a broken white line, by law you may overtake, so long as it is safe to do so.
