  2. Intersect at infinity
  3. Intersect within the magnet
  4. Intersect at the neutral points

A
Cannot interest at all
B
Intersect at the neutral points

Solution
Verified by Toppr

If field lines ever intersect at any point.
There will be two tangents to the field line curve at that point, which is contradictory, as there can only be one net magnetic field vector having only one direction at any point in space.
