The answer is
(d) The intensity of magnetic field in A is less than B.
We know,
R ~ 1/M
Resistance is inversely proportional to the intensity of the magnetic field.
In circuit A, the resistance is maximum as they are connected in series and thus intensity of magnetic field decreases.
In circuit B, the resistance is minimum as they are connected in parallel and thus intensity of magnetic field increases.
So, the correct answer is option (d).
