Curie temperature is the temperature above which

Curie temperature is the temperature above which
  1. Ferromagnetic material becomes diamagnetic material
  2. Ferromagnetic material becomes paramagnetic material
  3. Paramagnetic material becomes diamagnetic material
  4. Paramagnetic material becomes ferromagnetic material

Solution

Above curie temperature domains break down, hence ferromagnetic substances become paramagnetic.
