Correct Option: (A)
Direction of magnetic field can be found by applying Right Hand Thumb Rule.
 
Imagine that you are holding a current-carrying straight conductor in your right hand such that the thumb points towards the direction of current. Then, your fingers will wrap around the conductor in the direction of the field lines of the magnetic field. This is known as the right-hand thumb rule.
 
By applying this rule, you will get the direction of magnetic field from north to south.
