A small bar magnet is suspended freely from a thread near one end of a solenoid. Its orientation is shown in figure (i), when no current is flowing in the solenoid.

In figure (ii), the final position of the magnet is shown, when a large current flows in the solenoid.

Now, which of the following statements are incorrect for the situation shown in figure (ii)?
(i) The direction of the current in the solenoid is clockwise as observed from magnet side.
(ii) The direction of the current in the solenoid is anticlockwise from magnet side.
(iii) If the direction of the current is reversed there will be no effect in the position of the bar magnet.
(iv) If the solenoid is slowly moved away from the magnet to the left, the bar magnet will move to the right.

A(i) and (iii) only
B(ii) and (iv) only
C(i), (iii) and (iv) only
