(C) The magnetic field lines due to a current loop in the $xy$ plane pass through the center of the loop along the $z$-axis. At any point in the $xy$ plane (the plane of the coil),the magnetic field vector is perpendicular to the plane,meaning it has only a $z$-component. Thus,$B_y = 0$ at $z = 0$. As we move along the $z$-axis at a fixed distance $a$ from the $z$-axis (in the $yz$ plane),the magnetic field lines curve. For $z > 0$,the $y$-component of the magnetic field $(B_y)$ is positive,and for $z Therefore,the graph of $B_y$ versus $z$ must pass through the origin $(0,0)$ and show an antisymmetric behavior,which corresponds to the plot shown in option $C$.
