Solution
The correct option is B South
Using Right-hand thumb rule, the direction of magnetic field due to a straight wire is shown in the figure above. If we align our thumb in direction of current and curl our fingers anti-clockwise then at P out fingertips will point SOUTH.Thus magnetic field at point P points in the south direction i.e option B is correct.
