Solution
The correct option is A flipped
When a straight current-carrying conductor is clasped in such a way that the thumb points in the direction of the current, the direction in which the fingers wrap will be the direction of the magnetic field around the conductor.
Now if the direction of current is flipped, then the direction at which the fingers wrap, will be flipped.
