The correct statement about the energy stored in the magnetic field in this scenario is:

The increase in the energy stored in the system is proportional to the decrease in kinetic energy.

When the second bar magnet moves and aligns itself with the first magnet, it converts some of its kinetic energy into potential energy stored in the magnetic field. Therefore, as the kinetic energy of the second magnet decreases, the energy stored in the magnetic field increases.
