Two infinitely long straight wires lie in the xy-plane along the lines...

The given condition is represented by the figure as shown below:

(A) Due to two straight wires, the magnetic field at origin is zero because both the wires are located at same distance from the origin; thus, they cancel out magnetic field of each other. Therefore, only the magnetic field due to the circular loop act on the origin and its direction is in −k . So, the total magnetic field

could not be zero at origin.
(B) When I₁ > 0 and I₂ < 0 , the magnetic field due to the circular loop acting on the origin and its direction is in −k and the net magnetic field at origin due to both the straight wires is in + k direction. Thus it may be possible that they cancel out and make zero magnetic field at origin.
(C) When I₁ < 0 and I₂ > 0 , the magnetic field due to the circular loop acting on the origin and its direction is in −k and the net magnetic field at origin due to both the straight wires is in −k direction. So, the total magnetic field cannot be zero at origin.
(D) If I₁ =I₂ then B₁ =B₂ , then they cancel out each other at the center of the loop. So, only magnetic field exists due to the circular loop.
