Solution

The correct option is C
parallel to the axis of the solenoid

The magnetic field produced by a current-carrying solenoid is similar to the magnetic field produced by a bar magnet. They are straight lines parallel to the axis of the solenoid going from south pole to north pole inside the solenoid and from north pole to south pole outside the solenoid.
