Which of the following statements is correct?

materials exhibiting Meissner effect are diamagnetic and have $X=-1$ and $μ_r= 0$.

Materials that get weakly magnetised when placed in an external magnetic field and have $X>-1$ and $μ_r> 0$ are called ferromagnetic materials.

At high enough temperature, a paramagnet becomes a ferro magnet and gets strongly magnetised.

Super conductors are the ferromagnetic materials that are strongly repelled in an external magnetic field.
