(b) spirals
(c) parallel to the axis of the tube
(d) perpendicular to the axis of the tube

Solution

(c) parallel to the axis of the tube

The magnetic field lines in the middle of a current-carrying solenoid are parallel to the axis of the tube because magnetic field is uniform inside a solenoid.
