Where is the magnetic field strongest?
A. closest to the wire
B. Farthest from the wire

In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as 1/r1/r where rr is the distance from the wire. This can change a bit depending on the length and shape of the wire. Far enough away, the magnetic field decays as 1/r21/r2 .

what is the question here. i think you messed up.
