What is the difference between option A and B here?

B is for length & A is for current.

For perfect core coil, H=no.of turns x current.
For air core L or non-magnetizing core has,
H= constant value (u0=4 x 10 power -17).
MMF for length Force(H)= NI x L.
Flux density relation with MMF(H)=(NI X L)/B.
=> for also include Length.
BH=NI.=> for only current.
BH=u0.=> for constant value.
