In absence of magnetic field dipole moment of
Diamagnetic ferromagnetic and paramagnetic
Are respectively
Zero zero zero
Zero non zero zero
Zero zero non zero
Zero nonzero non zero
Pls explain this

Dear Student
Diamagnetic material looses their magnetism on removal of external magnetic field so in the absence of an external magnetic field, the net magnetic moment of diamagnetic substance is zero. 
In the absence of an external magnetic field, the magnetic moments of atomic magnets are randomly arranged, hence the net magnetic moment of the paramagnetic substance is zero.
Ferromagnetic materials are permanent magnets so in absence of external magnetic field too, magnetic moment of ferromagnetic material  is non-zero always.

So correct option should be 
zero, non - zero , zero
