Compressed Magnetic Fields Tend to Push Themselves Apart

Compressed magnetic fields tend to push themselves apart. Yet sunspots can be stable for as long as 2 months. How do we explain this?

A) Sunspots are stabilized by the circulation of charged gases around the field below the surface of the photosphere.
B) Sunspots tend to occur in pairs of opposite polarity. The repulsive forces tend to keep each group compressed.
C) The energy that is needed to push the field lines apart is instead expended in sending spicules into the chromosphere.
D) The sunspot pairs (preceding and following members) cancel out, relaxing the magnetic fields and their tendency to repel.
