Please explain the following 34th question with reason.

Dear Student,
34.
The magnetic dipole moment of a current carrying coil is:
μ = NIA
where, N = number of turns in the coil
I = current flowing through the coil
A = area of the cross section 
Hence, the magnetic dipole moment of a current carrying coil does not depend upon the material of the turn of the coil (option d).

Regards
