A square loop, carrying a steady current $I,$ is placed in a horizontal plane near a long straight conductor carrying a steady current $I_1$ at a distance $d$ from the conductor as shown in figure. The loop will experience
  • A
    a net attractive force towards the conductor
  • B
    a net repulsive force away from the conductor
  • C
    a  net torque acting upward perpendicular to the horizontal plane
  • D
    a net torque acting downward normal to the horizontal plane
