A "bar magnet" has a north and south pole associated with it. In this case the correct answer is D - the magnetic field lines start at the magnet's north pole and then extends down to the south pole of the magnet. Bar magnets are made from materials that are ferromagnetic and have an intrinsic magnetisation even in the absence of a magnetic field.
