Answer:
As per the thumb rule of magnetism and electricity, a current carrying wire or conductor which is straight produces concentric circles of the magnetic field.
Thus the choice "d” in the specified question is right.
Whenever current is produced in any type of conductor some magnetic fields are observed around it.
