Consider the effect of temperature on two materials 'P' and 'Q' as, with the rise in temperature, materials 'P' becomes diamagnetic, where 'Q' has no effect of temperature at all, then:
1
'P' is paramagnetic and 'Q' is diamagnetic
2
'P' is ferromagnetic and 'Q' is paramagnetic
3
'P' is paramagnetic and 'Q' is ferromagnetic
4
'P' is ferromagnetic and 'Q' is diamagnetic
