Here the direction of current towards west and towards North. So, by Flemming left hand rule the direction of magnetic field is upward. The rule used in Flemming left hand rule which states that if we stretch our thumb forefinger and middle finger of our left hand perpendicular to each other in such a way that forefinger points the direction of magnetic field and middle finger points the direction of current and middle finger points the direction of current then thumb will represent the direction of force.
So, the correct answer is upward.
