Three identical bars A, B and C are made...

Three identical bars A, B and C are made of different magnetic materials. When kept in a uniform magnetic field, the field lines around them look as follows:
Make the correspondence of these bars with their material being diamagnetic (D), ferromagnetic (F) and paramagnetic (P):

A

`A harrD, B harr P, C harr F`

B

`A harr F, B harr D, C harr P`

C

`A harr P, B harr F, C harr D`

D

`A harr F, B harr P, C harr D`
