Q1:

In paramagnetic materials

A permanent magnetic dipoles exist but the interaction between neighbouring dipoles is negligible

B permanent magnetic dipole do not exist

C permanent magnetic dipoles exist and the interaction between neighbouring dipoles is very strong

D permanent magnetic dipole moment may or may not exist

ANS:A - permanent magnetic dipoles exist but the interaction between neighbouring dipoles is negligible

In paramagnetic materials interaction between neighbouring dipoles is negligible.
