Solution

The correct option is A right hand thumb
The direction of magnetic field lines around a straight current-carrying wire is found out using the right hand thumb rule. If you hold the current carrying conductor in your right hand in a way that the thumb points in the direction of the current flow, the fingers encircle the conductor in the direction of the magnetic field generated either clockwise or counter-clockwise.
